Python: How to pip install opencv2 with specific version 2.4.9?

matchifang picture matchifang · Jun 8, 2017 · Viewed 282.1k times · Source

I know that I could pip install opencv-python which installs opencv3, but is there a separate command or name for opencv specific version such as 2.4.9?

If not, how can I specify which version to install?

Thanks.

Via pip you can specify the package version to install using the following:

pip install opencv-python==2.4.9

However, that package does not seem to be available on pypi.

A little trick for checking available versions:

pip install opencv-python==

Which returns:

Could not find a version that satisfies the requirement opencv-python== (from versions: 3.1.0.0, 3.1.0.1, 3.1.0.2, 3.1 .0.3, 3.1.0.5, 3.2.0.6, 3.2.0.7) No matching distribution found for opencv-python==
