COCO download script is broken

[lemairecarl]

In the resulting folder,

• annotations/instances_trainval35k.json.zip is corrupted (also why does the script downloads this but doesn't unzip it?)
• coco_labels.txt is missing (it can be found in ssd.pytorch/data)

There are no errors in the console output.

You can download that file on here. https://dl.dropboxusercontent.com/s/s3tw5zcg7395368/instances_valminusminival2014.json.zip After download, just change file's name correctly(instances_trainval35k.json) and copy that to correct directory(annotations/).

Then, you can train with MS COCO dataset.

I think we can only train this model on coco but we can not test and evaluate, am I correctly understood Thank you

@seongkyun I have followed your answer on my MBP2022. I got this error. OSX 13.4.1 (c) (22F770820d) Python 3.11.3 My packages pip freeze.txt

You forgot to mention extract and rename it 👎

Sorry but this link can't be found now. Can you please update it? Thanks!
