Runtime error: Loop not running

[dv-rastogi]

Hi! I am trying out the following code snippet (from Example.ipynb):

import dropboxdrivefs as dbx
token = 'some-token'
fs = dbx.DropboxDriveFileSystem(token=token)
with fs.open('/test-repo/tester.txt') as file:
     print(file.read())

I am running into the following error:

Traceback (most recent call last):
  File "code.py", line 118, in <module>
    print(file.read())
  File "~/mypy/lib/python3.8/site-packages/fsspec/implementations/http.py", line 566, in read
    return super().read(length)
  File "~/mypy/lib/python3.8/site-packages/fsspec/spec.py", line 1544, in read
    out = self.cache._fetch(self.loc, self.loc + length)
  File "~/mypy/lib/python3.8/site-packages/fsspec/caching.py", line 377, in _fetch
    self.cache = self.fetcher(start, bend)
  File "~/mypy/lib/python3.8/site-packages/fsspec/asyn.py", line 91, in wrapper
    return sync(self.loop, func, *args, **kwargs)
  File "~/mypy/lib/python3.8/site-packages/fsspec/asyn.py", line 46, in sync
    raise RuntimeError("Loop is not running")
RuntimeError: Loop is not running

Edit: It also fails with the same error if I directly create a dropbox file system:

fs = fsspec.filesystem(protocol='dropbox', token=token)
repo_files = fs.find('dropbox:///test-repo/')
with fsspec.open('dropbox:///test-repo/tester.txt', token=token) as f:
    print(f.read())

Kindly also note that other operations work fine, such as find, ls, etc. I am running into this issue with read only. Any and all help would be appreciated! Thanks!

Hello, It could be related to this issue https://github.com/fsspec/filesystem_spec/issues/844 A PR fixing it has been merged recently. Can you try with the code installed from the master branch to see if that fixed the error please? Thank you.

Hi @MarineChap. Thanks for the fix. It works! Will there also be a pypi release with the latest PR?

[MarineChap]

Super, good to know. @martindurant is the one who fix it.

About the release, @martindurant now that it is part of the fsspec project, do you need to be involved in the release process? Or can I just push a release on pypi manually as I did before ? I don't really have the time yet to setup a pipeline for it.

Not at al, do as you would have done. Please ensure that you update any links in setup.py , README, etc., if they weren't already.

Ok, then @watch24hrs-iiitd I will push a release with the fix before the end of the week.

That's great :). Thanks for an active response!

[MarineChap]

I have released on pypi a version 1.3.1. If everything is okay for you, I will close this issue.

Thank you for your feedback. Have a good day

[dv-rastogi]

The latest release incorporates the fixes. Thank you! :)
