Development

In case of adding a new tensorflow dataset or modifying the location of a zip file, it is necessary to update the url checksums. You can find the instructions in the following tensorflow documentation.

The steps to create the url checksums are the following:

1. Take the file with the dataset configuration (e.g. live_iqa.py) an place it in the tensorflow_datasets folder. The folder is commonly placed in ${HOME}/.local/lib/python3.8/site-packages if you install the python packages using the user flag.

2. Modify the __init__.py of the tensorflow_datasets to import your new dataset. For example from .image.live_iqa import LiveIQA at the top of the file.

3. In your terminal run the commands:

touch url_checksums/live_iqa.txt
python -m tensorflow_datasets.scripts.download_and_prepare  \
   --register_checksums  \
   --datasets=live_iqa

4. The file live_iqa.txt is going to contain the checksum. Now you can copy and paste it to your project’s url_checksums folder.
