Import Pandas throws up an error about berryconda

[jjhelmus]

@bonehead Can you provide more details on the environment where you are seeing this error? Specifically, what version of pandas and other packages are installed. The output of conda info and conda list should provide these details.

I was unsuccessful when I attempted to replicate this error on my machine using pandas 0.20.3-py36_0, pandas imported without error using this setup.

I'm not seeing anything obvious that would be causing an issue. Mixing pip and conda can cause some problems but in this case it does not seem to be the cause. It's possible that tslib.cpython-36m-arm-linux-gpuabihf.so file was corrupted or truncated at some point. Can you check the size of the file using ls -l /home/pi/berryconda3/lib/python3.6/site- packages/pandas/_libs/tslib.cpython-36m-arm-linux-gnueabihf.so. It should be 7001272, it is it not then something is amiss.

Removing and reinstalling pandas may fix the issue, conda remove pandas followed by conda install pandas should do the trick.

I purged Berryconda and reinstalled and it did the trick, Pandas reinstalls fine.
