Lightning GPU Installation

PennyLane Help
1

I’m trying to build using the PyPI/Conda installed cuQuantum package
In the second step, according to the tutorial, it should be python setup.py build_ext
But I don’t know which directory should enter the above command.

Hey @Cc1! You should clone the pennylane-lightning repo and run python setup.py build_ext within that repo. You should see a setup.py file once you clone it, which is what you need to run!

@Cc1 If you are using Conda, you may now install the pennylane-lightning-gpu package available on conda-forge. You can install it with mamba as follows

mamba create -n pll-gpu -c conda-forge pennylane-lightning-gpu

or with conda as follows

conda create -n pll-gpu -c conda-forge pennylane=0.29.0 pennylane-lightning-gpu

If you are using conda, you will likely to specify the pennylane version as above, because conda currently has a problem resolving the right version of pennylane.

Hi @Cc1
If you want to use the package without compilation, you can simply install it via:

python -m pip install cuquantum pennylane pennylane-lightning-gpu

If you are running on ARM or PowerPC you will need to build from source. Let us know if any of the above helps.
