Installing PyQT in conda environment

Question

The final goal was to have a working environment with: Tensorflow, numpy, pandas, pyqt5, psycopg2. I successfully installed TF, numpy and pandas but not pyqt5. That's what I did:

1. Installed X-Code command tools
2. Installed miniforge
3. installed Tensorflow via pip:

pip install --upgrade --force --no-dependencies https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl. 4. Installed pandas and numpy. 5. TRIED to install pyqt5 via conda install with: (1)conda install --name new_env pyqt5

(2)conda install --name new_env -c conda-forge pyqt5

(3)pip install pyqt

(4)pip install pyqt5

But none of that worked out. For commands (1) and (2) came out:

"PackagesNotFoundError: The following packages are not available from current channels:

• pyqt

Current channels:

• https://conda.anaconda.org/conda-forge/osx-arm64
• https://conda.anaconda.org/conda-forge/noarch

• https://repo.anaconda.com/pkgs/main/noarch
• https://repo.anaconda.com/pkgs/r/osx-arm64
• https://repo.anaconda.com/pkgs/r/noarch

While for (4) command:

ERROR: Could not find a version that satisfies the requirement pyqt (from versions: none) ERROR: No matching distribution found for pyqt

and (5):

I tried to be as specific as possible, my final goal was having a working version of Tensorflow on my Mac M1, along with a couple more packages like pandas, numpy, PyQT5 and psycopg2. I succeded to install Tensorflow, pandas and numpy, need help on PyQt5

Answer 1

Do not try to install "PyQt5" but just "PyQt". Add the version if necessary, but at the moment of writing 5 is still current.

Answer 2

I think this should work for the installation of PyQt5.

conda config --add channels conda-forge
conda config --set channel_priority strict
conda install pyqt

This should be done prior to using pip, as stated here.

Answer 3

Try with

conda update --all
conda install qt
conda install pyqt
