Hello @arunraja-hub , I have attempted several time to reproduce this bug without success.

Let me know if which steps you took.

Hi, I had the same issue earlier today too. In my case, if I downgrade the package fsspec v2023.9.2 to v2023.6.0, the error would be gone and everything works for me again.

(I am using molfeat v0.9.4)

Thanks @dyan-yen, I think it might be a bug recently introduced in fsspec. I believe they don't auto-create folder on file opening on write mode anymore. Should be easy to fix.
