Any progress on this? I'm noticing ``` with fsspec.open("s3://some-bucket/debug.txt", "wt") as f: f.write("test") ``` Failing with an error in the parent post, but the following workaround ``` with fsspec.filesystem("s3").open("s3://some-bucket/debug.txt", "wt")...

As before, I needed to RTFM. Bumping to the latest `s3fs` (and related packages) fixed this issue! Specifically, here are my related package versions: ``` s3fs==2021.10.0 fsspec=2021.10.0 botocore==1.20.106 aiobotocore==1.4.2 ```

Ah, it may be due to my CPU tensors not being in pinned memory: https://forums.developer.nvidia.com/t/does-cudamemcpyasync-require-pinned-memory/40411
