after conda update to dask 0.9.0 get ImportError: cannot import name gzip_compress

[twiecki]

Is there an additional package that's required?

[mrocklin]

That's odd. Can you show the full stack trace and the code used to produce the error?

ImportError: cannot import name gzip_compress

[mrocklin]

Does this work for you:

In [1]: from dask.compatibility import gzip_compress

[twiecki]

Ugh, restarting the kernel fixed it. Sorry for wasting your time.

[mrocklin]

No worries. In looking around for a solution I learned that we weren't doing future imports uniformly, resulting in #1158

[arita37]

Same issues, after installing dask.

  File "\Anaconda27\lib\site-packages\s3fs\core.py", line 23, in <module>
    trans.ReadTimeoutError, trans.IncompleteReadError

AttributeError: 'module' object has no attribute 'ReadTimeoutError'

[mrocklin]

@arita37 can you share

1. How you installed dask
2. Your python version
3. The version of dask that you have (by pip freeze)
4. The full traceback of the errors that you see?

Closing for now as stale. Feel free to reopen if you still have issues (preferably with the requested information above).
