I am writing a program that splits a video into frames and extract the text of every nth frame using opencv-python and pytesseract. I managed to get the code working, but the program was working rather slowly. I tried to use PyPy3 to improve performance but ran into an issue installing the opencv library for pypy.
This is the error code:

I feel like I tried everything. I successfully installed all other dependencies using
pypy3 -m pip install [package]
Yes, I already upgraded my pip, setuptools and wheels to the latest version.
Any other relevant information:
interpreter path: /usr/local/bin/pypy3
Python version: PyPy 7.3.9 [Python 3.7.13]
OS: MacOS
What I understand is that the error lies with building the wheels and I read something about building the package myself. I couldn't figure it out tho. Any help would be much appreciated.
EDIT:
I installed cmake using brew install cmake. Now when I try to install opencv-python, instead of raising an ERROR, the cmd gets stuck at
Building wheel for opencv-python (pyproject.toml) ... |
The error message states that it may be linked to cmake, You can try to install it. -> https://cmake.org/install/

TensorRT is not available for Windows via pip. You can verify that by looking at the wheel files in PyPI, link. All the wheel files for the latest version are for Linux. Thus, trying to install on Windows will pick the previous releases, which were place-holder packages. Those releases just print the message you are seeing, on all OSes.
According to the documentation
The zip file is the only option currently for Windows.
You can find instructions on how to install at Zip File Installation.
When I try to install the python typedb-client using pip, I get several errors concerning grpcio:

ASM Builds for BoringSSL currently not supported on: macosx-11.1-arm64
as well as many lines of:
...
distutils.errors.CompileError: command '/usr/bin/gcc' failed with exit code 1
...
This happens both on global installation and in conda environments...
After searching for grpcio installation issues on the M1 architecture, the solution for me was to prepend the following to the pip command:
export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1 export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1 pip install typedb-client==2.9.0
in some cases, should you see ssl errors, you can extend that command to:
CFLAGS="-I /opt/homebrew/opt/openssl/include" LDFLAGS="-L /opt/homebrew/opt/openssl/lib" GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1 GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1 pip install typedb-client==2.9.0
assuming that you have openssl install via homebrew. This tells pip where to look for appropriate headers and code to build the grpcio pip package.

There was no change in requirements.txt
Heroku recently updated setuptools to 60.10.0 for python build pack
However, the setuptools upgrade also drops support for the deprecated
use_2to3 feature, which may be used be a small number of legacy
dependency versions. This change occurred in setuptools 58.0.0
(released 2021-09-04), which we have deliberately not updated to for
as long as possible, in order to give any affected packages time to be
fixed. However it's no longer viable to delay updating any longer, due
to the pipenv compatibility issues.
The above pull request have some options to fix affected packages. In my case we didn't need anyjson anyway, removing it from requirements.txt fixed the problem
I had the same error, unfortunately the downgrade setuptools didn't help me. In my case, the solution was to uninstall the kombu package (ofc if you don't use Celery in your project)

error
In Python 2.xx, you can call print without parenthesis but in Python 3.xx, you need to call print with parenthesis. It seems like the version of pyaudio you are using is on Python 2.xx because the print statement where you are getting the error is missing parenthesis. Can you check your version of pyaudio? The latest version seems to be 0.2.11.
According to the error you are getting, you have not entered the other parenthesis at the end of the sentence. So try entering the missing parenthesis there.
If that doesn't work, try making another function like
def prn(text):
print(text)
And then calling that function instead of the print function there.

I'm very grateful if someone help solve this problem
I think psycopg2-binary package has been pre-built assuming that it would run on a Linux system which uses the glibc implementation as the standard C library. Termux runs on Android, which does not use glibc. So I think what is happening is that pip understands that and falls back to building psycopg from source, in which case the build dependencies should be installed before.
Try installing the build dependencies:
apt-get install libpq-dev gcc python3-dev musl-dev
See https://github.com/psycopg/psycopg2/issues/684
A web search for the same problem shows that this is also the case for other Linux systems that don't use glibc, like Alpine Linux.
