A dataset not found when I run "python script/pretrain.py -c config/pretrain/mc_gearnet_edge.yaml --gpus [0]"

It seems that the file located in "https://ftp.ebi.ac.uk/pub/databases/alphafold/latest/UP000006548_3702_ARATH_v2.tar" really doesn't exist. When I entered this url in my browser, it also noticed me that the file doesn't exist.

Oh, I found that on the web the dataset's version turns to v4 instead of v2. So If I just used v4 dataset, will it have an effect on the experiments? Addtionally, how did I use v4?

I think it's okay to use v4 instead of v2. The pre-training dataset doesn't have a large effect on the final performance.

I have downloaded the v4 dataset and put it into the correct directory. However, when I tried to run the command python script/pretrain.py -c config/pretrain/mc_gearnet_edge.yaml --gpus [0], the program still started to download the v2 dataset. I don't know how to deal with this condition.

[Oxer11]

Sorry for the inconvience! This is because I set the default files as v2 datasets instead of v4 datasets. The easiest way to change this is to inherit the datasets.AlphaFoldDB class and rewrite the urls and md5s attributes here. The class will check the downloaded files according to filenames in urls and check the md5 values.

I think this url issue is resolved in the updated version(0.2.1)
Installing the updated torchdrug fixed this
Use: pip install torchdrug==0.2.1
