- Following Installation Guide to build first.
For the windows user, please change the build config to
DLL. - Install with
cd python-package; python setup.py install
Note: Make sure you have setuptools
- Refer also to the walk through examples in python-guide folder
Trouble 1: I see error messages like this when install from github using python setup.py install.
error: Error: setup script specifies an absolute path:
/Users/Microsoft/LightGBM/python-package/lightgbm/../../lib_lightgbm.so
setup() arguments must always be /-separated paths relative to the setup.py directory, never absolute paths.
Solution 1: please check here.
The code style of python package follows pep-8. If you would like to make a contribution and not familiar with pep-8, please check the pep-8 style guide first. Otherwise, you won't pass the check. You should be careful about:
- E1 Indentation (check pep-8 link above)
- E202 whitespace before and after brackets
- E225 missing whitespace around operator
- E226 missing whitespace around arithmetic operator
- E261 at least two spaces before inline comment
- E301 expected 1 blank line in front of and at the end of a method
- E302 expected 2 blank lines in front of and at the end of a function or a class
You can ignore E501 (line too long).
