Using wheel files with conda
If you have software in a Python wheel file and want to use it with conda or install it in a conda environment, there are 3 ways.
The best way is to obtain the source code for the software and build a conda package from the source and not from a wheel. This helps ensure that the new package uses other conda packages to satisfy its dependencies.
The second best way is to build a conda package from the wheel file. This tells conda more about the files present than a pip install. It is also less likely than a pip install to cause errors by overwriting (or "clobbering") files. Building a conda package from the wheel file also has the advantage that any clobbering is more likely to happen at build time and not runtime.
The third way is to use pip to install a wheel file into a conda environment. Some conda users have used this option safely. The first 2 ways are still the safest and most reliable.
Building a conda package from a wheel file
To build a conda package from a wheel file, install the .whl file in the conda
You may download the .whl file in the source section of the conda recipe's
You may instead put the URL directly in the
pip install command.
It is important to
pip install only the one desired package. Whenever
possible, install dependencies with conda and not pip.
You must use the
--no-deps option in the
pip install command in order
to avoid bundling dependencies into your conda-package.
If you run
pip install without the
--no-deps option, pip will often
install dependencies in your conda recipe and those dependencies will become
part of your package. This wastes space in the package and increases the
risk of file overlap, file clobbering, and broken packages.
