Error

The following error appears out of Python 2.7.16 but not with Slicer python-real which is 2.7.13:

Traceback (most recent call last):
  File "diffusionQC/diffusionQC.py", line 57, in <module>
    QC.run()
  File "/home/tb571/miniconda2/lib/python2.7/site-packages/plumbum/cli/application.py", line 572, in run

    S = res.get()  # when pool.map_async
  File "/home/tb571/miniconda2/lib/python2.7/multiprocessing/pool.py", line 572, in get
    raise self._value
ValueError: Object arrays cannot be loaded when allow_pickle=False

Solution

Move to Python 3/Slicer 4.11 and see if this happens.
