Failed to install DeePMD on macOS Tahoe 26.2

[joezhang-rpi]

Hi Everyone,

Hope you are doing well.

When I tried to install DeePMD-kit on my MacBook Pro with Tahoe 26.2 using

$ conda create -n deepmd deepmd-kit lammps -c conda-forge

I always got stuck at the following message:

---

Collecting package metadata (current_repodata.json): done

The process just stopped at 'Solving environment'. Could you please help me with this?

Thank you in advance.

Sincerely,
Joe
