Data Collection Failed

I tried to use VTune to analyze TensorFlow (basically Python + C++) workload, and the python process died as soon as as I stared data collection (by pushing the Start button). The python process died with the message:
AMPLXE_TPSSCOLLECTOR: init1226: attach_notification_result == tpss_er_success : attach_notification_result = 14
Assertion failed: init1226: attach_notification_result == tpss_er_success : attach_notification_result = 14. Please contact the technical support. Segmentation fault (core dumped)
I also the message in VTune:
11435 : ERROR : Stack size provided to sigaltstack is too small. Please increase the stack size to 64K minimum. 
11435 : WARNING : Function 'PyEval_EvalFrameEx' can be analyzed incorrectly because it uses indirect branch instructions. 

I increased the stack size, but that didn't change anything.

Hello,

Can you please specify VTune and Python versions?
