Installing PyQT in conda environment

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:
Installed X-Code command tools
Installed miniforge
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:

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

Try with
conda update --all
conda install qt
conda install pyqt

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.

Error in updating AWS cli to latest version

I'm trying to update AWS CLI to the latest version. I'm following the below AWS documentation:

The command '/bin/sh -c pip3 install fastparquet' returned a non-zero code: 1
If I instead pip3 install numpy==1.11, there is no problem.
If I first upgrade pip3, then pip3 install fastparquet works but pip3 install fastparquet==0.3.2 gives the same error.

I fixed this by first installing setuptools==42.0.0, which switched to using pip to resolve setup_requires (https://setuptools.readthedocs.io/en/latest/history.html#v42-0-0). (fastparquet uses setup_requires to install numpy before its installed itself)

I am trying to install the python module pyobjus (this is the one that fails to install another module).
But I always get some bug during installation. I tried to switch to other python versions, reinstall pip, use option --no-cache-dir, etc, but couldn't manage to get past this bug:

Any help would be greatly appreciated.
My OS is Linux Mint 19.3.
I saw this question which is about the same problem, but following the links did not bring any answer. It says PyObjus is designed for MacOS, but then why does the module katrain, supposedly compatible with linux, tries to install it when running "pip3 install katrain" (giving the same error as above) ?
Edit adter Marat's suggestion:
I removed the test for ios, the installation goes a bit further, but fails because Python.h is missing. when trying to install python3-dev, apt-get says that broken packages such as python3.6-dev are flagged "left as is", so it cannot install the required ones. Is there a way to fix the python installation, which seems to be broken ? I am afraid to break all the system if I mess up with it too much, but there is clearly a problem with my installation...
Fixed the above issue by reinstalling stuff, now it is CoreFoundation.h that is missing...

Error when I try to install matplotlib on my Mac for Python [duplicate]

OS: Windows 10
Python ver: 3.9.0
Error code:
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
I tried:
python -m pip install -U pip
python -m pip install -U matplotlib
didn't work.
and then I tried:
pip install --upgrade setuptools
didn't solve the problem.
I read on SO that maybe if I open the shell in administrator mode it could solve the problem but it didn't work too.
I saw someone mentioning ez-setup for this error code. I installed it but that didn't work too.
I don't know if it has something to do but my C directory looks like this:
C:\Users\METİNUSTA
It has an uppercase i character which sometimes can cause problems with applications. I can't change it because I am using my school's Windows key and it don't let me do any change. Because of this I installed python on D: .
Also here my pip list for extra information:
ez-setup 0.9
flake8 3.8.4

pip 20.2.4

python -m pip install --upgrade pip
pip install matplotlib==3.3.1
Worked for me.

edit: matplotlib has now released wheels for python 3.9 so pip install --upgrade matplotlib should work.
original answer
matplotlib hasn't made a wheel yet for version 3.9 so your python attempted to build it from source. You should downgrade to python 3.8 and then everything should work

This is because matplotlib has no 3.9 wheels ..
For convenience in the use of matplotlib, you can install anaconda.
In anaconda environment matplotlib, numpy and pandas are available by default for Python installed in Anaconda.
Or you can use lower versions of Python.

Install it from the source (Python >= 3.9.2):
git clone git://github.com/matplotlib/matplotlib.git
and build and install with:
cd matplotlib
python -mpip install .
If you want to be able to follow the development branch as it changes just replace the last step with:
python -mpip install -e .
Source and more information here: https://matplotlib.org/stable/faq/installing_faq.html#install-from-git

Matplotlib has no wheel for python version 3.10.
If tried installing matplotlib in 3.10 version of python by
pip install matplotlib
Results in : Error: Building wheel for matplotlib (setup.py)..error
Matplotlib dependencies are met and they are as follow:
cycler = 0.10
kiwisolver = 1.0.1
numpy = 1.16
pillow = 6.2.0
pyparsing = 2.2.1
six = 1.5
python-dateutil = 2.7
Tried upgrading pip and install matplotlib
python -m pip install -U pip
python -m pip install -U matplotlib
Successfully installed pip-21.3.1
again it didn't install Matplotlib.
Hence Down-versioned Python to 3.9 and installed Matplotlib. For Python version upto 3.9 wheel is defined for Matplotlib, do use Python 3.9 and make sure pip is upgraded to available version it wont be problem to install matplotlib
