I'm trying to install this library from pip:
https://github.com/ipazc/mtcnn
When I run the suggested command, I get this error:

I had this same error when trying to pip install opencv-python. However, I resolved the issue by running sudo apt install python3-opencv successfully. The mtcnn packages tries to reinstall opencv with the pip method that fails. How do I get around this issue?
I am on an aws ec2 ubuntu 18.04.

First install Cmake by doing
pip install cmake
or
pip3 install cmake
Then install mtcnn
pip install mtcnn

but without success

Not sure if it's the reason for the error but considering the release notes of Numpy 1.18.1, you should have Cython ≥ 0.29.14 whereas the requirements.txt specifies Cython==0.29.13.
FROM python:3 results in getting Python 3.8.
The Python versions supported in this release are 3.5-3.8. Downstream
developers should use Cython >= 0.29.14 for Python 3.8 support and
OpenBLAS >= 3.7 to avoid errors on the Skylake architecture.

i have searched alot of websites but nothing is helping, if anyone have any idea or experience with openwhisk docker python actions please any help would be appreciated.
I have checked it by just installing numpy and its working perfectly but somehow when i add scipy and numpy both to install it throws me error that numpy module not found.
Thanks

Try using the python runtime kind python-jessie:3 it already contains some ML related packages like numpy, scipy, pandas, and scikit-learn
For example using the CLI to create an action
ibmcloud fn action update mymlaction mymlaction.py --kind python-jessie:3
More details on the python runtime here https://console.bluemix.net/docs/openwhisk/openwhisk_reference.html#openwhisk_ref_python_environments

Unable to download a package using Pip : says Cython not installed when it is

I am trying to download the pyahocorasick package on my Windows 10 system using pip.
On my command line, I wrote-
pip install pyahocorasick
It gave the following output -

Then I tried to see if Cython is in fact installed, so I wrote-
Cython version
and the output was -
Traceback (most recent call last):
File "C:\Python34\lib\runpy.py", line 170, in _run_module_as_main

from .Scanning import PyrexScanner, FileSourceDescriptor
ImportError: DLL load failed: %1 is not a valid Win32 application.
And finally I tried -
install Cython
And the output was -
Requirement already satisfied: Cython in c:\python34\lib\site-packages
So my question is - if Cython is already installed, why does installing the package pyahocorasick give the error - Cython does not appear to be installed? And how can I fix this problem?

can't change python version for pyside on Mac

I'm attempting to setup PyCharm with a library provided for my introductory computer science course, but it appears that because of my version of python I am unable to install PySide, which is necessary for the library's imports. python --version outputs
Python 3.5.1 :: Anaconda 4.0.0 (x86_64)
when I try to install pyside with pip install pyside I received the following error:

I've tried changing my version of python to 2.7, which looks like it would be supported, by installing pysel and running sudo pysel 2.7.12 but that gives me the following error:

BUT I'm certain I did install python 2.7.12, contrary to this error message. I tried reinstalling as a sanity check and confirmed that it IS installed:
brew install python
Warning: python-2.7.12 already installed
I've been wrestling with this for a few days now and it's really got me confused. My thought is that Anaconda might be causing a problem but I'm not sure. Any thoughts?
Edit: I've attempted to install pyenv per your suggestions and encounter the following error. Again, it looks like Anaconda is causing some conflict.
