segmentation fault error

I try to run the train.py, but the code fails on the line:

after reinstalling the anaconda, the problem is fixed.

when I run this code, there is an error 'Segmentation fault (core dumped)'.have you solved it? thank you for your reply！

Hi, have you solve this problem? I run into the same one, and don't know how to do. Looking forward to your reply!

The "segment fault error" occurs when I step into the forward function of the ROIAlign layer. Maybe it is about the version of some python dependencies. @rowanz, could you please provide the environment.yml file of your r2c conda env?

[rowanz]

can you double check that you've installed torchvision from the layers branch?

pip install git+git://github.com/pytorch/vision.git@24577864e92b72f7066e1ed16e978e873e19d13d

I changed the linux kernel and the problem is fixed. Thank you very much!

Hi, I have the same problem , how did you solve it? just reinstall anaconda?

[tanjatang]

finally I solved the problem by reinstalling anaconda and update cuda9 to cuda10
