Instructions how to install NUMPY and PANDAS on Termux

[sylirre]

Important: instructions provided in this post will not last forever and I will not update them for every new Python, Numpy or Pandas release.

Instructions confirmed to work as of 2024.10.10 on a system with these properties:

• CPU architecture: aarch64
• Android OS version: 14
• Termux version: 0.119.0-beta.1
• Python version: 3.12.7

Proceeding with steps described below, the following package versions were installed:

• Numpy: 2.1.2
• Pandas: 2.2.3

Instructions

Termux Wiki provides obsolete instructions at https://wiki.termux.com/wiki/Python, don't follow them.

Below is a set of commands for installing current versions Numpy and Pandas on a clean Termux installation. Read them carefully, don't re-order or modify steps unless know what you are doing. Steps are not applicable for old package versions.

1. Upgrade all packages

   yes | pkg upgrade
   

2. Install Python, dependencies and build tools

   pkg install python build-essential cmake ninja libopenblas libandroid-execinfo patchelf binutils-is-llvm
   

3. Install tools for building Python projects

   pip3 install setuptools wheel packaging pyproject_metadata cython meson-python versioneer
   

4. Check your Python version

   python3 -c 'import sys; print(f"{sys.version_info.major}.{sys.version_info.minor}")'
   

5. Install Numpy. Replace value 3.12 with actual Python version obtained in step 4!!!

   MATHLIB=m LDFLAGS="-lpython3.12" pip3 install --no-build-isolation --no-cache-dir numpy
   

6. Install Pandas. Replace value 3.12 with actual Python version obtained in step 4!!!

   LDFLAGS="-lpython3.12" pip3 install --no-build-isolation --no-cache-dir pandas
   

Common tips

Common tips when using pip in Termux:

• Pass --no-build-isolation if module requires cmake, ninja, patchelf or something like during build time.
• Pass --no-cache-dir to prevent reusing modules from cache. Useful in case you used wrong commands previously.
• Set variable LDFLAGS="-lpython3.12" to force link native extensions with Python 3.11 library (replace 3.12 with actual Python version). Needed at least for Numpy but other modules could require it as well.
• (!!!) Do not ever try to pip install --upgrade pip. If someone or something suggests to upgrade pip - IGNORE. Pip self-upgrade often suggested as a dumb-way troubleshooting, without getting into the depth of issue and often without knowing Termux environment specifics. Termux uses a patched variant of Pip which solves certain incompatibility issues. As Termux maintainers, we care about keeping it up-to-date.

(!!!) Do not ever try to pip install --upgrade pip.

So what's wrong with that?

[sylirre]

Because you'll get an original pip which is not suitable and doesn't contain runtime fixes to work properly in Termux.

You don't need to update it either. Termux will ship a newer version when required and users just need to run pkg upgrade.

If some module errored during pip install and suggested to upgrade pip, then ignore such messages. They are nothing more than just quick maintenance step to ensure environment sanity.

99.9% of pip errors inside Termux happen because of environment differences and missing dependencies. The post shows clearly steps to mitigate related issues for Numpy and Pandas. Similar steps could be applicable for other packages.

Thanks for clarifying

How to update Numpy?

[sylirre]

Reinstall newer version with MATHLIB=m LDFLAGS="-lpython3.11" pip3 install --no-build-isolation --no-cache-dir numpy

You still have to use additional variables and flags. No way to drop them.

[Duuckjing]

• Set variable LDFLAGS="-lpython3.11" to force link native extensions with Python 3.11 library (replace 3.11 with actual Python version). Needed at least for Numpy but other modules could require it as well.

What about changing the LDFLAGS to LDFLAGS="-lm -lcompiler_rt -lpython3.11" so as to ensure future numpy imports?

[sylirre]

As far I know, -lm -lcompiler_rt are no longer needed. These flags were required a while ago.

[frankiechan1977]

solved my problem. thanks so much.

It did not work! I did the exact steps in the instruction order, I even freshly installed termux from google play first. What happen was when I ran the following line code from the instruction above I received an error:
Code:
MATHLIB=m LDFLAGS="-lpython3.11.9" pip3 install --no-build-isolation --no-cache-dir numpy

I did the exact steps in the instruction order

MATHLIB=m LDFLAGS="-lpython3.11.9" pip3 install --no-build-isolation --no-cache-dir numpy

You definitely customized the steps.

Should be: MATHLIB=m LDFLAGS="-lpython3.11" pip3 install --no-build-isolation --no-cache-dir numpy

Attention to LDFLAGS specification.

I even freshly installed termux from google play first.

The app on Play Store is not ours. It belongs to https://github.com/termux-play-store/termux-apps and doesn't receive support from Termux developers team.

The latest Termux release is https://github.com/termux/termux-app/releases/latest

[sanousi]

Thank you for your response and time effort! Yes, I did customize the instructions "just a little bit" thinking it may be work, but it didn't! However the original instructions didn't work either, maybe because I have the false termux! I will get the original and try again with the exact instruction Best regards في الخميس، ١٨ يوليو ٢٠٢٤, ١٠:٠١ Git User ***@***.***> كتب:

I was able to install pygame with pip but couldn't install pygame-ce, but thanks to this topic I was able to do it.
pygame-ce is an active project that branched off from pygame for some reason,
and it asks you to uninstall pygame before installing pygame-ce, but I still couldn't install it properly.
However, after reading this and trying the same thing, I was able to install it.
I'll reported it so that someone other than me can find it through a search.

[glsup]

Thank you for the instructions! but it doesn't work for me, I'm getting:
../meson.build:1:0: ERROR: Compiler cc cannot compile programs.

I'm using Termux from F-droid.

Post literally says:

Set variable LDFLAGS="-lpython3.11" to force link native extensions with Python 3.11 library (replace 3.11 with actual Python version).

[sylirre]

Will refresh instructions later. Edit: instructions refreshed

[glsup]

thanks!
I thought that by passing the var "3.11" (as the commands in OP) it will install 3.11 (and not 3.12).
So do I need to replace them all with 3.12?

Also, how can I install it with 3.11?

[TomJo2000]

Also, how can I install it with 3.11?

We do not currently have a Python 3.11 package available for Termux,
as it is in the process of being moved to the TUR.
The PR working on that is

• new package: python3.11 termux-user-repository/tur#1230

[sylirre]

@glsup Statement LDFLAGS="-lpython3.11" is nowhere close to pkg install python3.11. It used only to instruct build system to force link with Python 3.11 library while building native extensions.

[jcharth]

i got termux on my s5 android 6. i just ran most of the pkg installs on this list but not all packages are there. i am trying to get opencv-python running. i was able to find the package in the termux version for new phones but not on the old one. hopefully after running all those pkg installs ill be able to pip install opencv-python. i am not even sure i will be able to but ill keep trying.

[sylirre]

Termux doesn't release new packages and updates for several years. That's why you can't install opencv-python with pkg.
