AccessDeniedException: 403 does not have storage.objects.list access to the Google Cloud Storage bucket.

[zwang92]

I am trying to follow https://github.com/mlcommons/training/blob/master/large_language_model/megatron-lm/README.md#data-download to download data on gs://mlperf-llm-public2 as following:
gsutil cp -r gs://mlperf-llm-public2/c4/en_val_subset_json/c4-validation_24567exp.json .

It fails with error message as following:
"AccessDeniedException: 403 xxx.xxx@gmail.com does not have storage.objects.list access to the Google Cloud Storage bucket. Permission 'storage.objects.list' denied on resource (or it may not exist)."

Could anyone give any suggestion on how to download gs://mlperf-llm-public2/c4/en_val_subset_json/c4-validation_24567exp.json ?

Thanks a lot
