Problems installing pybamm from conda forge

[AlvarmenTUD]

Hi all,

I am trying to install PyBaMM from Anaconda Prompt using
conda install -c conda-forge pybamm

I have created a new environment for this purpose with both python 3.9 and 3.8 but still not able, I am getting the following error:

Been trying to install the package for some time but I am getting this or other problems, doing it from anaconda navigator and from anaconda prompt.

I have tried with pip from windows powershell and still not able to install the package.

Any idea what can be the cause of these problems???
Thanks a lot in advance.

Use python 3.7 today, pip install is OK

@AlvarmenTUD please install wheel before installing pybamm using pip -

pip install wheel
pip install pybamm

@Jerry841124 please avoid using pybamm on Python 3.7. pybamm's latest releases do not support Python 3.7; hence, pip will fetch you an outdated version of pybamm on Python 3.7.

@Saransh-cpp May I ask which stable version is recommended? Thanks!

The latest pybamm version should usually be preferred - pybamm follows CalVer. You can use Python 3.8 or 3.9 with pybamm.

Dear all,

I had the latest python version (3.10) and was trying to install the newest version of pybamm (23). It appears that was the problem, not sure if it was something about the library itself or my computer.

I solved it by creating a new environment with python 3.9 and installing pybamm 22.12. With older versions in both, I was able to install and run it.

Hi! PyBaMM still does not support Python 3.10, only 3.8 and 3.9. The most recent versions should work with Python 3.9 as well.

Hi! I believe PyBaMM now does support Python 3.10, but I'm still having trouble installing the latest version 23.5 using conda-forge.

I've tested on MacOS (x64) and Linux, and conda-forge tends to pick version 0.2.3.post1.

Minimal example: conda create -n pybamm-exp -c conda-forge python=3.10 pybamm=23.5

Traceback:

UnsatisfiableError: The following specifications were found to be incompatible with each other:

However, the following options work:

• python 3.10 & pybamm 23.5 with pip

Thanks for reporting this! I believe https://github.com/conda-forge/pybamm-feedstock/blob/main/recipe/meta.yaml will require a few updates with the upcoming release too. Opening an issue for this.
