Unable to install GPU version of Pennylane-Qulacs

[JustinS6626]

Hi, I am trying to install Pennylane-Qulacs GPU with python3.11 and Pennylane.

My Pennylane info is as follows:

Name: PennyLane
Version: 0.35.0
Summary: PennyLane is a cross-platform Python library for quantum computing, quantum machine learning, and quantum chemistry. Train a quantum computer the same way as a neural network.

Location: /usr/local/lib/python3.11/dist-packages
Requires: appdirs, autograd, autoray, cachetools, networkx, numpy, pennylane-lightning, requests, rustworkx, scipy, semantic-version, toml, typing-extensions
Required-by: pennylane-qulacs, PennyLane_Lightning, PennyLane_Lightning_GPU

Platform info:           Linux-6.5.0-25-generic-x86_64-with-glibc2.35
Python version:          3.11.0
Numpy version:           1.26.3
Scipy version:           1.12.0
Installed devices:

When I enter

sudo pip3.11 install --upgrade qulacs-gpu

I get the following error:

      CMake Warning (dev) in CMakeLists.txt:
        No project() command is present.  The top-level CMakeLists.txt file must
        contain a literal, direct call to the project() command.  Add a line of
        code such as
      
          project(ProjectName)
      
        near the top of the file, but after cmake_minimum_required().
      
        CMake is pretending there is a "project(Project)" command on the first
        line.
      This warning is for project developers.  Use -Wno-dev to suppress it.

  note: This error originates from a subprocess, and is likely not a problem with pip.

I am wondering what this means, and how I can fix it. Thank you very much for your help.

Hi @JustinS6626! This looks like an error compiling Qulacs for GPUs on your system; unfortunately, we'll likely be unable to help you out here, as this looks to be an issue with Qulacs. I suggest opening an issue in the Qulacs GitHub here: https://github.com/qulacs/qulacs

[JustinS6626]

Thank you very much for getting back to me! I actually succeeded in overcoming the issue for Qulacs-GPU using the command

USE_GPU=Yes sudo pip3.11 install --no-build-isolation .

Could it work for pennylane-qulacs-gpu as well?
