Subject Re: pyarrow=0.3.0 now segfaults on parquet.write_table
Date Tue, 23 May 2017 23:10:45 GMT
hi Aneesh,

I've been updating the conda packages for arrow-cpp, parquet-cpp, and
pyarrow over the last 24 hours, so I suspect you've had bad luck with
the package stack getting into an intermediate state. There was a
build dependency problem on Windows that caused the delay.

conda install pyarrow=0.4.0 is now fully up to date on
Linux/macOS/Windows, so I recommend using that ASAP as it includes
important bug fixes.

If you are depending on these packages in your product, I would
_really_ appreciate some help maintaining the packages on conda-forge.
We probably need to do some work on the pinned versions in the
meta.yaml files so that the upgrade process does not disrupt existing
production applications.
