After "brew upgrade", I found I cannot use Pytables on my Mac.

Reason: image not found
I found that instead of having libhdf5.9.dylib in the directory, I have libhdf5.10.dylib now.
I can uninstall and install hdf5 without a problem and I also tried to reinstall tables.
I'm not sure how to solve this problem.
You need to reinstall tables. If you are using a recent version of pip, you also need to make sure you don't use a cached version of pytables that was built against the old libhdf. You can do this with pip install -U --force-reinstall --no-binary tables tables.
Problem solved by installing the developing version from GitHub:
pip install git+https://github.com/PyTables/PyTables.git#develop#egg=tables

I have a project using Python 3.10.4, i. e., the Pipfile has,
[requires]
python_version = "3.10.4"
I installed Python 3.10.4 using pyenv install 3.10.4 and now pyenv versions returns,
* system (set by /home/username/.config/pyenv/version)
3.10.4
Now when I run pipenv install I get,

The line Using /home/username/.config/pyenv/versions/3.10.4/bin/python3 (3.10.4) indicates that pipenv has found the right Python version and is using it to create the virtual environment but then when creating the lock file, observe that it uses the lib: /usr/lib/python3/dist-packages/pipenv/vendor/requests/utils.py directory is of the system installation. Which then causes the error since the system's lib is for Python 3.9.
Maybe this is a bug or maybe I have missed some config. Could someone see what is going wrong here?

Good news. As of this morning, you no longer have to use the setup_underactuated, and can install with pip, e.g. via
!pip install underactuated==2022.01.03
at the top of the notebook.
Unforunately, ngrok seems to have changed their support for unregistered connections, so you might still have to overcome this:

I am trying to build OpenCV from Source (master branch) using cmake.
I installed Eigen package via apt-get.
sudo apt-get install libeigen3-dev
It was successfully installed, and cmake prints that eigen 3.3.4 is installed.
Eigen: YES(ver 3.3.4)
But when I did 'make', it showed the error
/opencv/modules/core/include/opencv2/core/private.hpp:66.12: fatal error: Eigen/Core: No such file or directory
# include <Eigen/Core>
^~~~~~~~~~~~
compilation teminated.
I found the same question on superuser.
So as the answer did, I have changed cmake/OpenCVFindLibsPerf.cmake from line 44 to 59.
After I have commented out line 46-48 and 59,
and changed find_package(Eigen3 QUIET) in line 44 to find_package(Eigen3 3.0.0), it works.
And this problem only happens on OpenCV 4.0 version.
When I install OpenCV 3.4.6 version(tag 3.4.6 on github), this problem does not occur.
I'm trying to run a python script for a basic face recognition but when running after installing from pip I get the error:
QObject::moveToThread: Current thread (0x24c8e90) is not the object's thread (0x20da6d0).
Cannot move to target thread (0x24c8e90)
I found this question and it solved the problem but after that I get this error:
Traceback (most recent call last):
File "face_recognition.py", line 21, in
recognizer = cv2.face.LBPHFaceRecognizer_create()
AttributeError: module 'cv2.face' has no attribute 'LBPHFaceRecognizer_create'
I found many answers (for example) to this problem but all suggested to install the opencv-contrib-python package from pip.
How can I include the needed package from apt-get?
The code where I get the error:
import cv2
import numpy as np
recognizer = cv2.face.LBPHFaceRecognizer_create()
I tried installing Tweepy for python using homebrew by the command brew install tweepy But it showed the following error:
Error: No available formula with the name "tweepy"
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps. What command should I use?
Please don't suggest to use pip, I already tried that many times, couldn't succeed.
Edit:
Using pip install tweepy , results in following:

Unfortunately, Homebrew doesn't provide packages for python generally.
I have to say you should use pip.
