python3: can't open file '/tmp/pip-req-build-6jhijoew/tools/train_net.py

[2019ZSS]

I follow the instructions and install dependencies,
cd /YOLOF/playground/detection/coco/yolof/yolof.res50.C5.1x
But when I input:
pods_train --num-gpus 2
I get a problem:
python3: can't open file '/tmp/pip-req-build-6jhijoew/tools/train_net.py': [Errno 2] No such file or directory
this what happen?

Could you provide more details about how you install cvpods?

[2019ZSS]

according to https://github.com/megvii-model/YOLOF/blob/main/README_cvpods.md
just use command: pip install 'git+https://github.com/Megvii-BaseDetection/cvpods.git' --user

[chensnathan]

As we already include the cvpods package in this repo, you may install and run with the following steps:

git clone git@github.com:megvii-model/YOLOF.git
cd YOLOF/
python setup.py develop
cd ./playground/detection/coco/yolof/yolof.res50.C5.1x
pods_train --num-gpus 2

BTW, thanks for reporting this. Will refactor the codebase soon to avoid ambiguity.

Thanks for your reply.
I did as you said , but I get the same problem.
Maybe that's not the problem

[chensnathan]

If you follow the steps above, the error should not start with '/tmp/pip'. It will use the file for training whose path is YOLOF/tools/train_net.py. You can check that in the file YOLOF/tools/pods_train.

Have you uninstalled the previously installed cvpods before you re-install this repo? Or are there any errors that occur during the installation?

I reinstall cvpods and YOLOF to solve the above problem.
But when I run: pods_train --num-gpus 2
I get a new problem:

Traceback (most recent call last):

I try to install python-lvis module, but this is not useful.
