Segmentation fault due to _C.so file #26

Closed sandeep-ipk closed 5 years ago

sandeep-ipk commented 5 years ago

Hey @yikang-li,

The _C.so file in lib/layer_utils is giving a segmentation fault in all the files it is being called. For example, the first fault comes in lib/ayer_utils/roi_layers/nms.py (nms = _C.nms) file.

In conclusion, wherever the _C.so file is imported is giving me a segmentation fault. Could you perhaps help me out?

These are my settings: CUDA = 10.1 python = 2.7.16 PyTorch = 1.0.1 gcc = 5.2.0

Thank you very much, Sandeep.

Here is the fault:

Hey @yikang-li

I solved it by downloading Faster R-CNN PyTorch implementation. After that, I re-ran setup.py of its library, copied the _C.so files created from its compilation to the Factorizable Net's corresponding locations.

I can't think of an explanation of why this worked.

Best, Sandeep.

Hey @sandeep-ipk ! Can you precisely mention the steps I need to follow to get rid of this issue? Thanks in advance. :)
