Description

I'd like to install nd2 via conda-forge, but I'm getting a PackagesNotFoundError.

What I Did

Attempted to install nd2 into environment directly during environment creation and after creation using install command.

conda create -n py-nd2 -c conda-forge python=3.11 nd2

Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

i assume you're on an m1...

can you try the https://conda.anaconda.org/conda-forge/osx-64 channel? due to the way this package is bundled (the binaries are compiled outside of the conda build process) it's conceivable that the macos package there will work for you, even though it's not in the osx-arm64 channel

https://anaconda.org/conda-forge/nd2

Thanks! This worked. Correct, I'm using an m1.

It possibly goes without saying, but in case other m1 users see this and are planning to use nd2 with other packages (or an IDE such as spyder, as I am), you'll need to create a new environment that specifically uses the https://conda.anaconda.org/conda-forge/osx-64 channel to install all packages and ensure there aren't errors due to accessing the default arm64 files that conda install -n myenv -c conda-forge 'package-name' will automatically install.

Thanks for confirming, I'll try to get this fixed soon as well

[tlambert03]

with v0.6.0 (which is building on conda-forge at the moment), nd2 is now a pure python noarch package (there is no longer any C code being wrapped), so I expect this issue will go away
