Correcting for running Template-vision-segmentation in colab about code-generator

[vfdev-5]

@Jar199 thanks for reporting! Yes, we were also thinking at some point about enabling automatic dataset downloading. We didn't do that due to the fact that the dataset size is about several GBs and automatically downloading it can be seen as an unexpected behaviour vs using already downloaded dataset.

Maybe, we can add additional line to the README and into colab cell:

python -c "from data import download_datasets; download_datasets('/path/to/data')"

What do you think ?

I think that's a good idea!
That's a much better way to add command line like that than to change the code 🙃
