Unable to download pretrained weights

When running the following to download the pretrained weights:

```
cd ROOT_DIR/PreDiff
python ./scripts/download_pretrained.py --model all
```

There are two errors.
1. `sed: -e expression #1, char 31: unterminated `s' command`
2. The files are 2.4k and contain an Google Drive - Virus scan warning.

Example stdout:

```

When looking at `pretrained_sevirlr_vae_8x8x64_v1.pt` we see:

```

This also means the next step of course does not work:
```
cd ROOT_DIR/PreDiff
MASTER_ADDR=localhost MASTER_PORT=10001 python ./scripts/prediff/sevirlr/train_sevirlr_prediff.py --gpus 2 --pretrained --save tmp_sevirlr_prediff
```

Is there any chance you can store the data in S3?
