Hi All,
I build Slicer from trunk and pip_install(“tensorflow”) from python interactor within Slicer (Ctrl + 3).
Seems to be successful. Then I “import tensorflow”，but this crashes Slicer without detailed error message.
I tried this:
./Slicer --launch …/python-install/bin/python
Then in this python interpreter, I import tensorflow
And things are fine (no crashing)
But within Slicer it crashes.
Could I have any hint on the direction I should look into?
Thank you!

Importing tensorflow in Slicer GUI works fine on Windows (using a recent Slicer Preview Release - Slicer-4.11.0-2019-08-13).
What operating system and which Slicer version do you use? Do you have a stack trace of the crash? Have you pip-installed any other packages?
You may try to downgrade tensorflow or switch between GPU/CPU version.
Hi Andras,
I’m using Linux Mint 19.1 with gcc 7.3 with nightly Slicer (20190816)
I didn’t pip install other packages except those trigger by tensorflow.
I tried both GPU (tensorflow-gpu) and CPU versions and both crashes.
I don’t have crash trace yet. It just says :
./SlicerApp-real] exit abnormally - Report the problem.
How could I get the trace info?
Thanks!

I don’t know how to debug this on linux, hopefully others can help.
Alternatively, you can run your Python script as a CLI module. See example here.
Thank you Andras!
I’ll investigate the CLI python approach and update with you.
Best,

You could also generate a core dump and than open it with ddd (or gdb). While there are no debug info available within Release build, it should still provide some useful information.
See Documentation/Nightly/Developers/Tutorials/Debug Instructions - Slicer Wiki
Thanks Jc,
Will do this and report back soon.
Best,

Hi Andras,
In trying the python CLI, how could i assign the python environment I want Slicer to run my pythonCLI with? (Say my python exe is in /opt/anacondaGPU/bin/python)
Thanks for the advice!
Best,
