Subject Re: Unexpected keyword argument 'split_blocks'
Date Wed, 26 Aug 2020 14:59:46 GMT
Hi Jayant,

This keyword was introduced in pyarrow 0.16, so you will need to
update your installation.

For updating, if `conda update pyarrow` indicates it is already
installed, you can also try `conda install pyarrow=0.16`. However, it
might be you will need to use the conda-forge channel, as I am not
sure the default Anaconda channel has more recent versions of pyarrow
available (`conda update pyarrow --channel conda-forge`).


(note: I am sending it to the user mailing list as well, which I think
is the better place for this question)
