Re: Pyarrow installation--solved
Dear all,
Thanks for your input. This problem is now resolved.
1) removed older version of anaconda
2) reinstall anaconda3.7 and other packages
3) pip install pyarrow==0.15.*
The import of pyarrow is good now.
Before, I used 'condo install -c conda-forge pyarrow’, and Conda installed an older version 0.11.1 automatically, not the latest 0.15. It seems to me that the older version of pyarrow may result in the conflicts with other packages.
Best regards
Xiaoni

Re: Pyarrow installation--solved
Posted by xxwang <xi...@obspm.fr>.
Hi Igor,
Thanks for your reminding. I created a new environment and installed Pyarrow from conda-forge. Indeed the version 0.15 is installed automatically in the new enviroment. The import is all right.
Best regards

Re: Pyarrow installation--solved
Posted by Igor Yastrebov <ig...@gmail.com>.
Hi Xiaoni,
I strongly advise against doing it this way. If `conda install -c
conda-forge pyarrow` installs pyarrow 0.11.1 in your environment then it
means there is a conflict between versions of packages and you will likely
encounter problems later on.
I advise the following:
1) Remove anaconda
2) Install miniconda instead
3) Install only the packages you need (preferably in a new environment)
4) Do `conda install -c conda-forge pyarrow=0.15.1`
5) Success! If problems remain, resolve conflicts manually
Best regards,
Igor
