To retrieve these chunks from the Staging Area, we need to pass an array of these keys into tensorflow, per source type. This commit hacks these arrays into the feed_many Staging Area, as well as into the place where feed_many is fed with data. Ideally these key arrays should be defined on the hypercube. They are not for the following reasons: 1. They technically have shape something like (nsrc/chunksize,), which is not a hypercube dimension. 2. Technically get fed per visibility chunk, so *technically* they should have shape (nsrc/chunksize, ntime, nbl, nchan). This would involve instantiating an array for the entire space of values, which might be possible (virtually) with dask, but still. 3. The partitioning scheme currently assumes that anything with a source dimension belongs to that source, rather than the feed_many array. Something should be done about this... --- montblanc/impl/rime/tensorflow/RimeSolver.py | 16 ++++ montblanc/tests/test_dist_mb_2.py | 92 ++++++++++++-------- 2 files changed, 74 insertions(+), 34

Some projects use tag names that include more than just the version +string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool +needs to strip the tag prefix to extract the version identifier. For +unreleased software (between tags), the version identifier should provide +enough information to help developers recreate the same tree, while also +giving them an idea of roughly how old the tree is (after version 1.2, before +version 1.3). Many VCS systems can report a description that captures this, +for example `git describe --tags --dirty --always` reports things like +"0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the +0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has +uncommitted changes. + +The version identifier is used for multiple purposes: + +* to allow the module to self-identify its version: `myproject.__version__` +* to choose a name and prefix for a 'setup.py sdist' tarball + +## Theory of Operation + +Versioneer works by adding a special `_version.py` file into your source +tree, where your `__init__.py` can import it. This `_version.py` knows how to +dynamically ask the VCS tool for version information at import time. + +`_version.py` also contains `$Revision$` markers, and the installation +process marks `_version.py` to have this marker rewritten with a tag name +during the `git archive` command. As a result, generated tarballs will +contain enough information to get the proper version. + +To allow `setup.py` to compute a version too, a `versioneer.py` is added to +the top level of your source tree, next to `setup.py` and the `setup.cfg` +that configures it. This overrides several distutils/setuptools commands to +compute the version when invoked, and changes `setup.py build` and `setup.py +sdist` to replace `_version.py` with a small static file that contains just +the generated version data. + +## Installation + +See [INSTALL.md](./INSTALL.md) for detailed installation instructions. + +## Version-String Flavors + +Code which uses Versioneer can learn about its version string at runtime by +importing `_version` from your main `__init__.py` file and running the +`get_versions()` function. From the "outside" (e.g. in `setup.py`), you can +import the top-level `versioneer.py` and run `get_versions()`. + +Both functions return a dictionary with different flavors of version +information: + +* `['version']`: A condensed version string, rendered using the selected + style. This is the most commonly used value for the project's version + string. The default "pep440" style yields strings like `0.11`, + `0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section + below for alternative styles. + +* `['full-revisionid']`: detailed revision identifier. For Git, this is the + full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac". + +* `['date']`: Date and time of the latest `HEAD` commit. For Git, it is the + commit date in ISO 8601 format. This will be None if the date is not + available. + +* `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that + this is only accurate if run in a VCS checkout, otherwise it is likely to + be False or None + +* `['error']`: if the version string could not be computed, this will be set + to a string describing the problem, otherwise it will be None. It may be + useful to throw an exception in setup.py if this is set, to avoid e.g. + creating tarballs with a version string of "unknown". + +Some variants are more useful than others. Including `full-revisionid` in a +bug report should allow developers to reconstruct the exact code being tested +(or indicate the presence of local changes that should be shared with the +developers). `version` is suitable for display in an "about" box or a CLI +`--version` output: it can be easily compared against release notes and lists +of bugs fixed in various releases. + +The installer adds the following text to your `__init__.py` to place a basic +version in `YOURPROJECT.__version__`: + + from ._version import get_versions + __version__ = get_versions()['version'] + del get_versions + +## Styles + +The setup.cfg `style=` configuration controls how the VCS information is +rendered into a version string. + +The default style, "pep440", produces a PEP440-compliant string, equal to the +un-prefixed tag name for actual releases, and containing an additional "local +version" section with more detail for in-between builds. For Git, this is +TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags +--dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the +tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and +that this commit is two revisions ("+2") beyond the "0.11" tag. For released +software (exactly equal to a known tag), the identifier will only contain the +stripped tag, e.g. "0.11". + +Other styles are available. See [details.md](details.md) in the Versioneer +source tree for descriptions. + +## Debugging + +Versioneer tries to avoid fatal errors: if something goes wrong, it will tend +to return a version of "0+unknown". To investigate the problem, run `setup.py +version`, which will run the version-lookup code in a verbose mode, and will +display the full contents of `get_versions()` (including the `error` string, +which may help identify what went wrong). + +## Known Limitations + +Some situations are known to cause problems for Versioneer. This details the +most significant ones. More can be found on Github +[issues page](https://github.com/warner/python-versioneer/issues). + +### Subprojects + +Versioneer has limited support for source trees in which `setup.py` is not in +the root directory (e.g. `setup.py` and `.git/` are *not* siblings). The are +two common reasons why `setup.py` might not be in the root: + +* Source trees which contain multiple subprojects, such as + [Buildbot](https://github.com/buildbot/buildbot), which contains both + "master" and "slave" subprojects, each with their own `setup.py`, + `setup.cfg`, and `tox.ini`. Projects like these produce multiple PyPI + distributions (and upload multiple independently-installable tarballs). +* Source trees whose main purpose is to contain a C library, but which also + provide bindings to Python (and perhaps other languages) in subdirectories. + +Versioneer will look for `.git` in parent directories, and most operations +should get the right version string. However `pip` and `setuptools` have bugs +and implementation details which frequently cause `pip install .` from a +subproject directory to fail to find a correct version string (so it usually +defaults to `0+unknown`). + +`pip install --editable .` should work correctly. `setup.py install` might +work too. + +Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in +some later version. + +[Bug #38](https://github.com/warner/python-versioneer/issues/38) is tracking +this issue. The discussion in +[PR #61](https://github.com/warner/python-versioneer/pull/61) describes the +issue from the Versioneer side in more detail. +[pip PR#3176](https://github.com/pypa/pip/pull/3176) and +[pip PR#3615](https://github.com/pypa/pip/pull/3615) contain work to improve +pip to let Versioneer work correctly. + +Versioneer-0.16 and earlier only looked for a `.git` directory next to the +`setup.cfg`, so subprojects were completely unsupported with those releases. + +### Editable installs with setuptools <= 18.5 + +`setup.py develop` and `pip install --editable .` allow you to install a +project into a virtualenv once, then continue editing the source code (and +test) without re-installing after every change. + +"Entry-point scripts" (`setup(entry_points={"console_scripts": ..})`) are a +convenient way to specify executable scripts that should be installed along +with the python package. + +These both work as expected when using modern setuptools. When using +setuptools-18.5 or earlier, however, certain operations will cause +`pkg_resources.DistributionNotFound` errors when running the entrypoint +script, which must be resolved by re-installing the package. This happens +when the install happens with one version, then the egg_info data is +regenerated while a different version is checked out. Many setup.py commands +cause egg_info to be rebuilt (including `sdist`, `wheel`, and installing into +a different virtualenv), so this can be surprising. + +[Bug #83](https://github.com/warner/python-versioneer/issues/83) describes +this one, but upgrading to a newer version of setuptools should probably +resolve it. + +### Unicode version strings + +While Versioneer works (and is continually tested) with both Python 2 and +Python 3, it is not entirely consistent with bytes-vs-unicode distinctions. +Newer releases probably generate unicode version strings on py2. It's not +clear that this is wrong, but it may be surprising for applications when then +write these strings to a network connection or include them in bytes-oriented +APIs like cryptographic checksums. + +[Bug #71](https://github.com/warner/python-versioneer/issues/71) investigates +this question. + + +## Updating Versioneer + +To upgrade your project to a new release of Versioneer, do the following: + +* install the new Versioneer (`pip install -U versioneer` or equivalent) +* edit `setup.cfg`, if necessary, to include any new configuration settings + indicated by the release notes. See [UPGRADING](./UPGRADING.md) for details. +* re-run `versioneer install` in your source tree, to replace + `SRC/_version.py` +* commit any changed files + +## Future Directions + +This tool is designed to make it easily extended to other version-control +systems: all VCS-specific components are in separate directories like +src/git/ . The top-level `versioneer.py` script is assembled from these +components by running make-versioneer.py . In the future, make-versioneer.py +will take a VCS name as an argument, and will construct a version of +`versioneer.py` that is specific to the given VCS. It might also take the +configuration arguments that are currently provided manually during +installation by editing setup.py . Alternatively, it might go the other +direction and include code from all supported VCS systems, reducing the +number of intermediate scripts. + + +## License + +To make Versioneer easier to embed, all its code is dedicated to the public +domain.

As no common ancestor existed, no data would be available for the iterator to consume. Changed the workflow to create a QueueResource which, in turn, is consumed by the QueueDataset, then consumed by the Dataset iterator. Thus, QueueResource is the common ancestor for both the Dataset and the enqueuing operation. --- .../rime_ops/simple_queue_dataset.cpp | 386 +++++++++++++----- .../rime_ops/test_simple_queue_dataset.py | 137 +++++++ .../rime_ops/test_simple_queued_dataset.py | 102 ----- 3 files changed, 411 insertions(+), 214 deletions(-) create mode 100644 montblanc/impl/rime/tensorflow/rime_ops/test_simple_queue_dataset.py delete mode 100644 montblanc/impl/rime/tensorflow/rime_ops/test_simple_queued_dataset.py diff --git a/montblanc/impl/rime/tensorflow/rime_ops/simple_queue_dataset.cpp b/montblanc/impl/rime/tensorflow/rime_ops/simple_queue_dataset.cpp index 85f4dc531..4690f561e 100644 --- a/montblanc/impl/rime/tensorflow/rime_ops/simple_queue_dataset.cpp +++ b/montblanc/impl/rime/tensorflow/rime_ops/simple_queue_dataset.cpp @@ -1,3 +1,5 @@ +#include + #include "tensorflow/core/framework/dataset.h" #include "tensorflow/core/framework/common_shape_fns.h" #include "tensorflow/core/framework/partial_tensor_shape.h" @@ -11,165 +13,325 @@ namespace montblanc { namespace { -// See documentation in ../ops/dataset_ops.cc for a high-level -// description of the following op. -

instead of Datasets After some mucking about with Datasets and tf.while_loop's, go back to using a bare GPU MapStagingArea for source data (lm, stokes), for the moment. A current limitation of tensorflow iterators is that it's not really possible to use them in a tf.while_loop construct. So one can't really loop over a Dataset containing source info at present. However, do use tensorflow Datasets for the data for each visibility chunk, which is much larger and leverages Dataset prefetch to GPU capabilities. --- .../rime/tensorflow/staging_area_wrapper.py | 27 ++++++++++++++----- montblanc/impl/rime/tensorflow/tf_graph.py | 21 +++++++++++---- 2 files changed, 36 insertions(+), 12 deletions(-) diff --git a/montblanc/impl/rime/tensorflow/staging_area_wrapper.py b/montblanc/impl/rime/tensorflow/staging_area_wrapper.py index 661a4225e..f2a8b2e57 100644 --- a/montblanc/impl/rime/tensorflow/staging_area_wrapper.py +++ b/montblanc/impl/rime/tensorflow/staging_area_wrapper.py @@ -1,12 +1,21 @@ -from attrdict import AttrDict +from six import string_types +from attrdict import AttrDict import tensorflow as tf from tensorflow.python.ops import data_flow_ops from queue_wrapper import _get_queue_types class StagingAreaWrapper(object): - def __init__(self, name, fed_arrays, array_schemas, shared_name=None, ordered=False): + def __init__(self, name, fed_arrays, array_schemas, + shared_name=None, ordered=False, + device=None): + + if device is None: + device = tf.DeviceSpec() + elif isinstance(device, string_types): + device = tf.DeviceSpec.from_string(device) + self._name = name self._fed_arrays = fed_arrays self._array_schemas = array_schemas @@ -14,18 +23,22 @@ def __init__(self, name, fed_arrays, array_schemas, shared_name=None, ordered=Fa # Infer types of the given fed_arrays self._dtypes = [array_schemas[n]["dtype"] for n in fed_arrays] + # Create placeholders for the fed arrays - self._placeholders = placeholders = [tf.placeholder(dt, - name="{n}_placeholder".format(n=n)) + self._placeholders = placeholders = [ + tf.placeholder(dt, + [None]*len(array_schemas[n]['dims']), + name="{n}_placeholder".format(n=n)) for n, dt in zip(fed_arrays, self._dtypes)] self._put_key_ph = tf.placeholder(dtype=tf.int64) self._get_key_ph = tf.placeholder(dtype=tf.int64) self._peek_key_ph = tf.placeholder(dtype=tf.int64) - self._staging_area = sa = data_flow_ops.MapStagingArea( - self._dtypes, names=fed_arrays, ordered=ordered, - shared_name=shared_name) + with tf.device(device): + self._staging_area = sa = data_flow_ops.MapStagingArea( + self._dtypes, names=fed_arrays, ordered=ordered, + shared_name=shared_name) self._put_op = sa.put(self._put_key_ph, {n: p for n, p in zip(fed_arrays, placeholders)}, diff --git a/montblanc/impl/rime/tensorflow/tf_graph.py b/montblanc/impl/rime/tensorflow/tf_graph.py index 8c93dab87..b0cde91b7 100644 --- a/montblanc/impl/rime/tensorflow/tf_graph.py +++ b/montblanc/impl/rime/tensorflow/tf_graph.py @@ -610,7 +610,8 @@ def _construct_tensorflow_expression(cfg, device): device = tf.DeviceSpec.from_string(device) # Partition input arrays - (source_data_arrays, feed_many, + (source_data_arrays, + feed_many, feed_once) = _partition(('utime', 'vrow'), input_schema()) feed_multiple = toolz.merge(feed_once, feed_many) @@ -618,13 +619,16 @@ def _construct_tensorflow_expression(cfg, device): # Create the graph with tf.Graph().as_default() as graph: multiple_dataset = _create_queue_dataset_details(feed_multiple, device) - source_datasets = {k: _create_queue_dataset_details(v, device) for k, v - in source_data_arrays.items()} + + source_staging_areas = {k: create_staging_area_wrapper('%s_cpu' % k, + v.keys(), input_schema(), + ordered=True, device=device) + for k, v in source_data_arrays.items()} TensorflowExpression = attr.make_class("TensorflowExpression", - ["multiple_dataset", "source_datasets", "graph"]) + ["multiple_dataset", "source_staging_areas", "graph"]) - return TensorflowExpression(multiple_dataset, source_datasets, graph) + return TensorflowExpression(multiple_dataset, source_staging_areas, graph) import unittest from dataset import input_schema, output_schema @@ -667,5 +671,12 @@ def _dummy_data(ph): result = S.run(mds.next_op) self.assertTrue(sorted(result.keys()) == sorted(mphs.keys())) + pds = expr.source_staging_areas['point'] + + feed_dict = {ph: _dummy_data(ph) for ph in pds.placeholders } + feed_dict.update({pds.put_key_ph: 2}) + S.run(pds.put_op, feed_dict=feed_dict) + S.run(pds.get_op, feed_dict={pds.get_key_ph: 2}) + if __name__ == "__main__": unittest.main() From 182b6286bea5633bb06926e52d5974eebfb56cdd Mon Sep 17 00:00:00 2001 From: Simon Perkins Date: Wed, 4 Apr 2018 14:57:55 +0200 Subject: [PATCH 227/416] Add internal schema For the purposes of defining internal (not user-facing) data.

+0200 Subject: [PATCH 272/416] Support empty input lists in create_antenna_jones Inputs to CreateAntennaJones may or may not be present. In order to reasonably support this, we use tensorflow mechanism that allows a list of tensors to be passed as an input -- an empty list implies absence of that input here. --- .../rime_ops/create_antenna_jones_op.h | 2 +- .../rime_ops/create_antenna_jones_op_cpu.cpp | 145 +++------- .../rime_ops/create_antenna_jones_op_cpu.h | 216 ++++++++------ .../rime_ops/create_antenna_jones_op_gpu.cuh | 263 ++++++++++-------- .../impl/rime/tensorflow/rime_ops/shapes.h | 6 +- .../rime_ops/test_create_antenna_jones.py | 15 +- 6 files changed, 311 insertions(+), 336 deletions(-) diff --git a/montblanc/impl/rime/tensorflow/rime_ops/create_antenna_jones_op.h b/montblanc/impl/rime/tensorflow/rime_ops/create_antenna_jones_op.h index a0fe9c3e4..c99ab0b1f 100644 --- a/montblanc/impl/rime/tensorflow/rime_ops/create_antenna_jones_op.h +++ b/montblanc/impl/rime/tensorflow/rime_ops/create_antenna_jones_op.h @@ -19,7 +19,7 @@ MONTBLANC_CREATE_ANTENNA_JONES_NAMESPACE_BEGIN template class CreateAntennaJones {};

JonesMultiply, the number of output dimensions is hard-coded to 5, so that (source,time,ant,chan,corr) can be handled. However, the user may want some smaller output e.g. (time,corr). Previously, dimensions missing in the input were simply assigned a size of one in the output. This commit allows: 1. Custom output schemas. For example (source,row,chan,corr) in the baseline case. 2. The ability to squeeze dimensions from the output. --- .../tensorflow/rime_ops/jones_multiply_op.h | 2 + .../rime_ops/jones_multiply_op_cpu.cpp | 29 +++++++++-- .../rime_ops/jones_multiply_op_cpu.h | 51 ++++++++++++++----- .../rime_ops/jones_multiply_op_gpu.cuh | 50 +++++++++++++----- .../rime_ops/jones_multiply_op_utils.cpp | 13 +++-- .../rime_ops/tests/test_jones_multiply.py | 29 ++++++----- 6 files changed, 129 insertions(+), 45 deletions(-) diff --git a/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op.h b/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op.h index bbf99842b..aec2af3a1 100644 --- a/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op.h +++ b/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op.h @@ -18,6 +18,8 @@ MONTBLANC_NAMESPACE_BEGIN MONTBLANC_JONES_MULTIPLY_NAMESPACE_BEGIN +constexpr int MAX_TENSOR_NDIM = 5; + // General definition of the JonesMultiply op, which will be specialised in: // - jones_multiply_op_cpu.h for CPUs // - jones_multiply_op_gpu.cuh for CUDA devices diff --git a/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op_cpu.cpp b/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op_cpu.cpp index 2d3d77a69..139b8415c 100644 --- a/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op_cpu.cpp +++ b/montblanc/impl/rime/tensorflow/rime_ops/jones_multiply_op_cpu.cpp @@ -24,13 +24,17 @@ auto shape_function = [](InferenceContext* c) std::unordered_map dim_sizes; std::vector input_shapes; - TF_RETURN_WITH_CONTEXT_IF_ERROR(c->input("in", &input_shapes), - "Unable to obtain input in"); + TF_RETURN_WITH_CONTEXT_IF_ERROR(c->input("jones_in", &input_shapes), + "Unable to obtain input jones_in"); std::vector str_schemas; TF_RETURN_WITH_CONTEXT_IF_ERROR(c->GetAttr("schemas", &str_schemas), "Unable to obtain schemas"); + bool squeeze; + TF_RETURN_WITH_CONTEXT_IF_ERROR(c->GetAttr("squeeze", &squeeze), + "Unable to obtain squeeze"); + std::string str_output_schema; TF_RETURN_WITH_CONTEXT_IF_ERROR( c->GetAttr("output_schema", &str_output_schema), @@ -86,8 +90,24 @@ auto shape_function = [](InferenceContext* c) for(auto & name: output_schema) { + // Was the given dimension in the input? auto it = dim_sizes.find(name); - out_dims.push_back(it == dim_sizes.end() ? c->MakeDim(1) : it->second); + + // No + if(it == dim_sizes.end()) + { + // Ignore it if we're squeezing + if(squeeze) + { continue; } + + // Otherwise add a singleton dimension + out_dims.push_back(c->MakeDim(1)); + } + // Yes + else + { + out_dims.push_back(it->second); + } } c->set_output(0, c->MakeShape(out_dims)); @@ -97,13 +117,14 @@ auto shape_function = [](InferenceContext* c) // Register the JonesMultiply operator.
