Problems in using pre-trained models

[liverishabh]

Hi @hpanwar08 ,
I was trying to use your pre-trained models for prediction by following your instructions and using the below command:

python demo/demo.py --config-file configs/DLA_mask_rcnn_X_101_32x8d_FPN_3x.yaml --input "<path to image.jpg>" --output <path to save the predicted image> --confidence-threshold 0.5 --opts MODEL.WEIGHTS <path to model_final_trimmed.pth> MODEL.DEVICE cpu

I am using Google Colab for the work and I am getting this error:

Traceback (most recent call last):

Found the issue.
Thanks for this great repository

Hey, sometimes I miss the notifications. Was the problem related to wrong model file?

[liverishabh]

Yeah, sort of.
I was using wget to download the models to colab and it was getting downloaded in zipped format (although the extension was still '.pth').

got caught by this as well. thanks!
