[Jimmybear-123]

HI! Thank you for your open source! I am trying to run examples you written in your document, but after input the code, it remind me an error named "ModuleNotFoundError: No module named 'chamfer'". How can I fix it? Looking for your help.

Hi,

This issue can be solved by installing extensions again, details can be found in #6

[Jimmybear-123]

Thank you for your reply! I have tried #6, run "python setup.py install --user" in /extensions/chamfer_dist/. I back to the /PoinTr-master/ and run the terminal. I input "bash install.sh", and I try run"bash ./scripts/test.sh 0
--ckpts ./pretrained/PoinTr_ShapeNet55.pth
--config ./cfgs/ShapeNet55_models/PoinTr.yaml
--mode easy
--exp_name example"
But the prompt is still the same. No module named 'chamfer'
I am confused, and Looking for your help.
Thank you.

This is weird, the same problem can be solved with this situation before.
Could you create a new virtual env and try it again?

[Jimmybear-123]

Thank you for your reply! I solved this error. I delete whole project, and do it again, this error was gone. But There's another error. Nijia is required to load C++ extensions. And I am working on it.

Oh, thank you! I run "sudo apt install ninja-build", and the problem has been solved!
