PennyLane Help
1

Hi, i have recently upgraded my pennylane version to 0.24 and i am facing following error when importing it

del ar.autoray._FUNCS["torch", "linalg.eigh"]
KeyError: ('torch', 'linalg.eigh')

i also have it if i install an older version too.
Does someone knows a way around?
thanks
best wishes

Hi @Oriel,

Thanks for opening this topic.

Can you please share some more code or explain what you’re looking to do here?

PennyLane works with Autoray 0.3.1 but not with versions 0.2.5 and older.

Hi, some things l learnt along the way to install jax properly:

  • use python3.9
  • on mac, install jax with conda ‘conda install jax -c conda-forge’

hope it helps

Hi @Oriel, thank you for sharing these insights!

@Vaishnavi_Chandilkar, as I just responded here unfortunately you would need to use PennyLane v0.15.1 if you want to keep using Python 3.6. If possible the best option is to upgrade your Python and use the latest PennyLane version available.

Thank you @CatalinaAlbornoz . I upgraded the python version and it worked!
