The ipynb provided here:

To Reproduce

The program just exits with a segmentation fault and no other output.

@ppwwyyxx Updated the comment. I tried on two different machines but it leads to the same segmentation fault.

Cannot import detectron2.utils.collect_env means that you have issues in your installation of pytorch/opencv/torchvision etc. It's best if you could clean up your environment, uninstall and reinstall all dependencies. If you're unable to do so, you can also use the provided dockerfile.

If you know how to use gdb, running gdb --args python -m detectron2.utils.collect_env and bt when it crashed can tell you more about which software in your environment is causing the crash.

@saksham15082 how did you resolve it? I am having the same problem

@batrlatom your issue is in fact more similar to #62 than this.
