Where can I get conda-pypi mapping file?

[gapplef]

I can't add any pypi dependence due to failed to fetch conda-pypi mapping.

pixi add --pypi lisa-data-challenge
Error:   × failed to map conda packages to their PyPI equivalents. This mapping is required when using PyPI dependencies alongside conda packages.
  ├─▶ failed to fetch conda-pypi mapping from remote source
  ├─▶ error sending request for url (https://conda-mapping.prefix.dev/hash-v0/81f2f246c7533b41c5e0c274172d607829019621c4a0823b5c0b4a8c7028ee84)
  ├─▶ client error (Connect)
  ├─▶ tcp connect error
  ╰─▶ Network unreachable (os error 101)

And the url in the error message is always Error 404

I found that this mapping is configurable in manifest.

But where can I get these mapping file? Is there any official place or third-party mirror that I can find these files?

Due to the network unreachable error, it seems to be something more. Could you check if this location is reachable for you: https://conda-mapping.prefix.dev/hash-v0/a4a7dab8db4dc81c736e9a9b42bdfd97b087816e029e221380511960ac46c690

Also could you send us the pixi.lock before you try to add this PyPI package? It might give us a clue why this particular hash is failing.

If you want to use the simplified mapping logic, you can get or use the file here: https://github.com/prefix-dev/parselmouth/blob/main/files/compressed_mapping.json

@ruben-arts Thanks for the help!

1. The location you provide is reachable for me.

2. After some simple tests, I found three different cases
   2.1 error with failed mapping, and reachable url

   pixi init
   pixi add python=3.13 cuda-toolkit=12.4.*
   pixi add --pypi bbhx-cuda12x 
   

   2.2 error with failed mapping, and 404 url

   pixi init
   pixi add python lalsimulation
   pixi add --pypi lisa-data-challenge
   

   here is the lock file pixi.lock.yaml

   And also

   pixi init
   pixi add python healpy
   pixi add --pypi pycbc
   

   here is the lock file pixi.lock.yaml

   3.3 Also uncommon, I also encounter situation where things change between these two case.
