model's parameters going to be empty

❓ Questions and Help

Hello all

When I do execution the code below in my ubuntu terminal, I get the error RuntimeError: stack expects a non-empty TensorList. I am trying to train the model using MS-COCO 2017 datasets (train2017, val2017, test2017).
python tools/train_net.py --config-file "configs/rotated/e2e_ms_rcnn_R_50_FPN_1x.yaml" SOLVER.IMS_PER_BATCH 2 SOLVER.BASE_LR 0.0025 SOLVER.MAX_ITER 720000 SOLVER.STEPS "(480000, 640000)" TEST.IMS_PER_BATCH 1

This is my dependencies for this rotated_maskrcnn.

Could you give me any tips?

Best regards

Thanks.

From the traceback it would seem like your model.parameters() is empty.
Either that or clip_grad_norm has changed API. This repo has been tested on 1.0, 1.1. Not tested on torch 1.5

@mrlooi I am curious that what version of python did you use? I am working with conda to follow your step-by-step installation but it is not working in my docker of nvidia/cuda-9.0-devel

It should work with python 2 and 3. Have you changed your torch version to 1.0 or 1.1?

@mrlooi Yes I tried to run your code after changing the torch version. I tried many times but I am still stuck for the environment setting. Now I am trying to use your Docker files.
I failed to make docker image from your Dockerfile in dockerfile folder. Now I am trying with docker-jupyter.

Could you give me comment consistently when I give you errors??
I am very worried that you are getting irritated by my questions.

Anyway, thank you so much for your comment so far. :)

Hey no problem, I wouldn't use the docker file, it's not updated.
If I were you, I'd have a look into the model.parameters() output, and see if it's empty. If it's empty, it means perhaps your model didn't load properly somewhere. If not, it's probably still the API change and perhaps your torch version is still not correct? Double check that your interpreter is using the right torch version.
At the end, if all else fails, try running on python2.7 or python3.5/3.6. Sorry I can't be of much more help here
