Unexpected keyword argument 'split_blocks'

[Jayant Singh <ja...@gmail.com>]

Good Evening,
My name is Jayant and I am using pyarrow version 0.15.0 with python 3.8 on
my MacOs catalina, latest version. As per the documentation (link
<https://arrow.apache.org/docs/python/pandas.html>), I ran following code
to avoid memory doubling;

df=table.to_pandas(split_blocks=True, self_destruct=True)

But I am getting the error;  to_pandas() got an unexpected keyword argument
'split_blocks'

Then I tried to update the package using: `conda update pyarrow` in the
terminal, I got a message all packages are already installed.

Kindly let me know how the above problem can be solved.

 Help is appreciated.

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`).

Best,
Joris

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