How to install PyPi packages using anaconda conda command
Solution 1
If you want to build conda packages for PyPI packages, the recommended way is to use conda skeleton pypi package
and use conda build package
on the recipe that it creates. To install the package, use conda install --use-local package
(here and elsewhere, package
is the name of the PyPI package you wish to install).
You will need to update the recipe each time the package is updated.
You can also use pip
to install these packages. There are two disadvantages: firstly, these packages won't be managed by conda at all. Secondly, these packages will not work if your default python version is different from the python version you are using in conda.
Solution 2
I will disagree with the accepted response and note that pip install [some-pypi-package]
is often the best way to install PyPi packages in Conda environments.
While the packages won't be managed by the Conda package manager, they will still be managed by the Anaconda environment. It will download the correct version of the package for the active Python install and update it correctly using the pip
package manager.
When using Anaconda, you should turn to conda
before pip
when you can, but you don't lose any of the replicability benefits of using Anaconda when you use pip
.
Anaconda recently published a doc that supports this: https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#using-pip-in-an-environment
Solution 3
Since version 4.6.0, Conda has improved its interoperability with pip:
Conda and pip have historically had difficulties getting along. Pip hasn’t respected Conda’s environment constraints, while Conda has been all too happy to clobber pip-installed software. It’s a mess. Conda 4.6.0 adds preview support for better interoperability. With this interoperability, Conda can use pip-installed packages to satisfy dependencies, and can even remove pip-installed software cleanly and replace them with Conda packages when appropriate. There’s still room for improvement before pip and Conda are hunky-dory BFFs, but we hope this is a good start. This feature is disabled by default right now because it can significantly impact Conda’s performance. If you’d like to try it, you can set this condarc setting:
conda config --set pip_interop_enabled True
So, the way to get PyPI packages into conda (at the time of writing this) seems to be:
pip install <package>
If you want conda to replace the PyPI packages with its own (where possible), just run:
conda update --all
Given that the above setting is made. Conda marks its own channels as higher priority than pip, thus packages will be replaced.

When using the Anacoda Python distribution, what is the best way to install a PyPi package that isn't available directly through Anaconda? For now I'm using:
conda pipbuild [pypi_name] conda install --use-local [package_spec]
But I'm unclear if this is the best way and if
conda update --all
will update these packages when updates are made available. I'm also unclear what the point of binstar is when PyPi already exists. -
user1507844 about 9 yearsThanks! Dumb question: what does condo managing the packages get me? Dependency management mostly? Automatic updates? Also, why is the method you described preferable to what I described above?
-
asmeurer about 9 yearsconda managing things gets you the benefits of dependency management. It also makes it easier to use that package with conda environments. Updates won't happen "automatically" (in the sense that you do need to type
conda update
for that to happen). As to why it's preferable,conda skeleton
is much more stable thanconda pipbuild

endolith over 8 yearsIt doesn't say this in conda.pydata.org/docs/using/… it just says
pip install x
. should those instructions be updated? -
endolith over 8 yearsand is there a way to have conda manage binary packages like lfd.uci.edu/~gohlke/pythonlibs/#scikits.audiolab ?

conda convert
can convert Gohlke's packages to conda packages conda.pydata.org/docs/commands/build/conda-convert.html -
Nathan Lloyd almost 8 yearsFinal command to install the package:
conda install --use-local package

Bryce Guinta about 7 yearsNote that you may need to run
conda install conda-build
to get theconda skeleton
command (I'm using miniconda). -
ws_e_c421 about 6 yearsOne issue to be aware of with this: If a
pip
package requires a different version of a dependency already installed byconda
,pip
will replace the installed package, andconda
won't realize its package has been removed. For a one-shot, scripted environment setup, this is probably fine. For an environment that you install into by hand over time, you will likely end up confused after a while. -
ws_e_c421 about 6 yearsOne way to mitigate the issue I mentioned above: save the output of
pip freeze
toconstraints.txt
and then install withpip
usingpip install -c constraints.txt <package>
. This will preventpip
from removingconda
packages. It will also pinpip
packages. Thepip
packages could be filtered out ofconstraints.txt
by looking at the output ofconda list
for the items marked as<pip>

Chris Conlan about 6 yearsFor things like Django, I’ll set up a virtual environment using Anaconda then do installations purely through pip for reasons mentioned above. Pure conda works best for getting a scientific computing stack together that uses conda channels.

NichtJens about 4 yearsWhat's your conda version? You can check via
conda --version
. I would presume your version is simply older than 4.6.0... -
asmeurer about 4 years@astabada, the package manager is called "conda" and the packages are called "conda packages". "Anaconda" is a distribution of conda packages, and not the only way to use conda.
