Issue: Import error installing with ppc64le
State: closed
Labels: name: bug

## Describe the bug
Installing the datasets library with a computer running with ppc64le seems to cause an issue when importing the datasets library.


```
python
Python 3.6.13 | packaged by conda-forge | (default, Sep 23 2021, 07:37:44) 
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import datasets
Illegal instruction (core dumped)
```

Error when importing
`Illegal instruction (core dumped)`

## Steps to reproduce the bug
I get this error when installing the library by using conda.  I can't install with pip I believe because pyarrow only has the ppc64le library on conda forge
```
conda create --name transformers_py36_v2 python=3.6 
conda activate transformers_py36_v2 
conda install datasets 
```

## Tracebacks
conda create --name transformers_py36_v2 python=3.6


```

## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->
- `datasets` version: 1.12.1
- Platform: Red Hat Enterprise Linux 8.2 (Ootpa)
- Python version: 3.6
- PyArrow version: pyarrow - 5.0.0 - py36h7a46c7e_8_cpu - conda-forge


Any help would be appreciated! I've been struggling on installing datasets on this machine.


This seems to be an issue with importing PyArrow so I posted the problem [here](https://issues.apache.org/jira/browse/ARROW-14323), and I'm closing this issue.
