python crashes when defining Trainer #2844

Open MMRohe opened 6 years ago

MMRohe commented 6 years ago

Hey,

I am running CNTK on python on windows 10. I try to run a code (that used to run correctly) on a new machine. When the code goes to this line:

trainer = C.Trainer(y, (loss_function, eval_function), learner, progress_writers)

Python crashes with the following message: Python has stopped working A problem caused the program to stop working correctly....

with no further info.

Any idea what that might be ? The code is running correctly on other hardware so I do not really understand. And also why does it stop at this specific line.

This is the setup in case it helps find the problem Selected GPU[0] Tesla V100-PCIE-16GB as the process wide default device. Build info:

I came across with the same error when I am trying to run run_fast_rcnn.py example. ANy idea what might be the reason?

I hit the same issue when running the CNTK tutorials, CNTK_103B and CNTK_103C. Crashes when it gets to trainer = C.Trainer(...). 100% repro. CTNK 2.5 CPU only.

Are you using CNTK for Python ? CNTK 2.5 release requires users installing OpenCV, MKL and CUDA. Crashes can happen if they are not properly configured. Check https://docs.microsoft.com/en-us/cognitive-toolkit/Setup-Windows-Python?tabs=cntkpy25

I had encountered the same issue with CPU-Only CNTK2.5, but once MKL was separately installed, this crash was resolved.
