Why does pip install not work for catboost?

I have to install catboost but can not make it by pip install catboost.

There is not catboost library in Anaconda, so pip in the one way.

The error message is:

Could not find a version that satisfies the requirement catboost <for version: >
No matching distribution found for catboost.

Python version is 3.6.3.

Screenshot of error:

error message

I’ve tried :

pip install catboost==0.12.2
pip install catboost==0.12.1.1
pip install catboost==0.12.1
pip install catboost==0.12.0

and

pip install catboost==0.11.0
pip install catboost==0.10.2

None of these works.

Why does this problem appeared and is there another way to install catboost?

Answer

From the docs

Installation is only supported by the 64-bit version of Python.

You need to reinstall the 64 bit version of python to use the cat boost package
