Permission Issue: Not able to access data in the Colab example

[ltejedor]

Hello, using the Colab example from this project's README.

On line: !source scripts/prepare_data.sh I get the error:

/usr/local/lib/python3.10/dist-packages/gdown/parse_url.py:44: UserWarning: You specified a Google Drive link that is not the correct link to download a file. You might want to try `--fuzzy` option or the following url: https://drive.google.com/uc?id=1L_We51j5FwIo5PeLvAK_9I3ZuFU_IWAq

When I go to the link directly, I'm able to see the files but not download them. Please help :)

I have access to the GrabNet data here - https://grab.is.tue.mpg.de/download.php - but there's a lot of it! I'm not sure which part corresponds to the Google Drive link referenced above.

Hi @ltejedor, Thanks for your interest in our work. I just checked Google Drive link for the files and it works fine on my end. Also, on our website, there are two download sections: 1. the GRAB dataset (you don't need this). 2. The GrabNet dataset (you should download this. Then please use the unzip code from our repo to extract the data. Please follow the instruction and it should work fine. Please see the snapshot below for the data required to train GrabNet.

Thank you for the reply. Did you try to use the Colab? While the Drive link loads, I'm not able to download or actually access any of the files, which I believe is leading to the Permissions issue referenced above.

I updated the colab notebook, now you should be able to manually download the file and put it in the right folder to continue.
