Trouble installing

[John-Krause]

I installed anaconda 3.0 and then tried to install pyart with:

conda install -c conda-forge arm_pyart

I got this error:

Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve.
Solving environment: unsuccessful attempt using repodata from current_repodata.json, retrying with next repodata source.

Can someone suggest a better install method?

@John-Krause - what version of python do you have installed in your environment?

[John-Krause]

john.krause@hops:~$ python --version
Python 3.11.4

[mgrover1]

and what platform is this on? Mac, Windows, or Linux? Can you a conda list and post the output here?

[mgrover1]

I would also recommend updating your anaconda versions, or consider switching to mambaforge distributions

• Mambaforge download (recommended) https://github.com/conda-forge/miniforge#mambaforge
• Anaconda release notes https://docs.anaconda.com/free/anaconda/reference/release-notes/

[John-Krause]

eventually (hours later......) the flexible solver figured it out:

Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve.
Solving environment: done

Proceed ([y]/n)?

[mgrover1]

Yeah, I suspect migrating to mamba here would help! You can install it using

conda install mamba

then

mamba install arm_pyart

or the package of your choosing. It utilizes parallel solving + a C++ codebase.

[zssherman]

I second the mamba install as well. I've also run into the solver stall with older environments as well, depending on the environment etc, might need a new environment as well.

[mgrover1]

@John-Krause - did any of those suggestions work?

[John-Krause]

eventually (hours later......) the flexible solver figured it out:

I did not attempt any other installation methods

[mgrover1]

Sounds good - I am glad it finally resolved
