anaconda-project generates different lock files on different systems

sandhujasmine commented 1 year ago

This appears to be an issue with anaconda-project but logging it here since if effects this repo. Setting up the examples-gallery-manage environment per the docs gets version consistent version of anaconda-project on osx, and linux-64:

$ conda list anaconda-project
# packages in environment at /home/jsandhu/miniconda3/envs/examples-gallery-manage:
#
# Name                    Version                   Build  Channel
anaconda-project          0.11.1             pyhd8ed1ab_0    conda-forge

I generated a lock file on OSX, and two Linux boxes with 3 different results - specs below:

# OSX uname -a

Lock file generated on OSX: anaconda-project-lock-osx.yml.txt
Lock file generated on HP Linux: anaconda-project-lock-hp-linux.yml.txt
Lock file generated on linux laptop: anaconda-project-lock-linux.yml.txt

Unsure why (2) and (3) are not the same but the lock files generated on the two linux systems successfully create envs on the two linux systems. I have not looked too deeply into the package variation between these linux systems as yet.
The hash in the lock files is the same which is a little confusing since the packages are slightly different we can see this by doing a diff.
Using the lock file generated on the Linux laptop seems to successfully create envs and start the project on all three systems. See errors reported below:

You're using the landsat project, right? What does conda info return on each of these systems?

sandhujasmine commented 1 year ago

It is indeed the landsat project. The different versions of conda appears to be the culprit. Thank you @AlbertDeFusco I hadn't updated my conda versions and I see now that anaconda-project lock would use the base conda installation's API to do the solve, hence the difference, is that correct?

I updated conda to the latest on OSX, regenerated the lock file and it now passes on the CI linux instances, which is what was causing the odd failures for me previously.

Does it make sense to include a conda as a dependency in this env file: https://github.com/holoviz-topics/examples/blob/main/envs/environment.yml#L10 along with anaconda-project? Or would that lead to more issues and confusion? Or maybe document some troubleshooting tips to ensure conda version is the latest. End user should ideally use the same conda version that is being run on the CI system.

AlbertDeFusco commented 1 year ago

Interesting. 🤔 What version of conda was causing the problem on osx? Were you using an M1 or intel miniconda?

sandhujasmine commented 1 year ago

Aah - I'm sorry, I should've run conda info before trying things out. I do have the installers I used on OSX and the HP Linux system so I'll share the conda version from those

Version on OSX: Miniconda3 py310_23.1.0-1
On the HP: Miniconda3 py310_22.11.1-1

On my linux-64 that built the previous lock file that worked on all 3 systems:

While the lock file that I generated on OSX w/ conda version 23.5.0 is able to create the env on linux-64 without an issue. I'm surprised to get slightly different packages when I use the same version of conda (see conda info output below) to generate lock file on the HP linux-64 machine vs OSX-M1.
