I’m pretty new to python. I came across holoviz and it seemed like a handy tool to learn about. However I’m struggling to get the initial environment setup to be able to run the tutorial. I’m using the latest 64-bit windows install of ananconda3 (currently 2020.11).
I followed the setup instructions for holoviz verbatim, but when I am testing the setup in 00_Setup.ipynb, the last cell results in the “SNAPPY is missing, so data cannot be read.” message. If I try to continue on anyways to 02_Building_Panels, the first cell fails on the call to dask.dataframe.read_parquet with: “RuntimeError: Please install either fastparquet or pyarrow”.
I then tried just running “import fastparquet as fp” to see if that would work. This gave me the following error: “ImportError: cannot import name ‘BaseMaskedDtype’ from ‘pandas.core.arrays.masked’ (C:\Users\me\anaconda3\envs\holoviz-tutorial\lib\site-packages\pandas\core\arrays\masked.py)”
It seems like there is some kind of package version incompatibility occurring… I found this thread that sounds similar to the problem I am having, but I’m not trying to use conda-forge, and I don’t quite understand the whole env.yml thing. Can anyone suggest an easy way to get past this?
