I am aware of this similar question, but that is on Windows and not for Mac M1, and their solution didn't work for me.
Aim
I would like to be able to use the python package oct2py.
Set Up and Problem
I have a new Mac M1. I have installed Anaconda using the 64-Bit (M1) Graphical Installer (316 MB). I have created an environment env-name, activated it, and installed oct2py using the command conda install -c conda-forge oct2py. In Python, when running from oct2py import octave or simply import oct2py it fails with the following traceback
Traceback (most recent call last):

I have coded a mathematical model and want to solve it using DOCPLEX module. My interpreter is Python 3.7. However, after doing a lot of effort, I will face the following error:

I have already run the following codes in my Pycharm's terminal:
cd C:\Program Files\IBM\ILOG\CPLEX_Studio201\python
python setup.py install
or
cd C:\Program Files\IBM\ILOG\CPLEX_Studio201\python
python setup.py install --home C:\Users\xxx\PycharmProjects\pythonProject\venv\Lib\site-packages\cplex
Finally, I also set the path variables of my own username to something like below:
"C:\Program Files\IBM\ILOG\CPLEX_Studio129\cplex\python\3.6\x64_win64" and
"C:\Program Files\IBM\ILOG\CPLEX_Studio129\cplex\bin\x64_win64\cplex.exe"
In my case I upgraded to python 3.8 and solved the issue
or you can use this:
pip install docplex==2.15.194
The problem is that python setup.py install does not guaranty that the python interpreter you are using is the same as your virtual env.
You need to activate your env before you run the install script.
Please open a Terminal then run:
C:\Users\xxx\PycharmProjects\pythonProject\venv\Scripts\activate
Then you can
cd C:\Program Files\IBM\ILOG\CPLEX_Studio201\cplex\python
pip install .
Docplex has a check_list.py script, which helps diagnose presence and location of cplex versions. In a terminal where Python is present, type
$ python -m docplex.mp.check_list
The answer looks like:
* system is: Windows 64bit
* Python version 3.7.8, located at: C:\python\anaconda2020.02\envs\docplex37\python.exe
* docplex is present, version is 2.20.204
* CPLEX library is present, version is 12.10.0.0, located at: C:\OPTIM\cplex_distrib\cplex1210R0\python\3.7\x64_win64
* pandas is present, version is 1.1.4
From the check list output you posted, I can see that you installed cos201.
Docplex need the Python/Cplex interface located inside cos, in your case:
C:/Program Files/IBM/ILOG/CPLEX_Studio201/cplex/python/3.7/x64_win64
This path should be added as a content root in your Pycharm project (File/Settings/Project Structure -> add content root
To check this, open a Python console tab in Pycharm, and try
import cplex
Once you add the right path , this should work.
You can then run the check list from within the console:
from docplex.mp.check_list import run_docplex_check_list
run_docplex_check_list()
Once this works, your program should solve OK inside Pycharm.
This said, I see your version of docplex is 2.15, which is older than CPLEX 20.1. You should update DOcplex to the latest version, which is compatible with CPLEX 20.1.
all,
I've installed the package:pywinauto successfully with "pip install pywinauto", but it always fails, why?
I did it in this way:
pip install pywinauto
and then under the windows cmd env, I run the python:
and then:
import pywinauto
I got the following errors:
....

WindowsError: [Error -2147312566] Error loading type library/DLL
It looks like you're using old OS Windows version like Windows XP. MS UI Automation is included into Windows Vista and later. But you may install .NET Framework 3.0+ to get UIAutomationCore.dll available even on Windows XP. If you don't need MS UI Automation technology at all, just run pip uninstall comtypes and pywinauto will work with Win32 API only.
If installing .NET Framework 3.0+ doesn't help (or if it's already installed) and you need to use Win XP, install Windows update KB971513. It solved the loading library issue for me.
I need upgrade the Winxp to Win7 or Win8, or Win10.
I have Python 2 and Python 3 installed on my system.
I run the following script:
#!/usr/bin/env python
import nxt.locator
from nxt.motor import *
def spin_around(b):
m_left = Motor(b, PORT_B)
m_left.turn(100, 360)
m_right = Motor(b, PORT_C)
m_right.turn(-100, 360)
b = nxt.locator.find_one_brick()
spin_around(b)
with the command: python spin.py which uses Python 2, as expected.
However, when I run this command I get the following error:
Traceback (most recent call last):
File "spin.py", line 12, in <module>
b = nxt.locator.find_one_brick()
File "/Library/Python/2.7/site-packages/nxt/locator.py", line 112, in find_one_brick

File "/Library/Python/2.7/site-packages/usb/core.py", line 1263, in find
raise NoBackendError('No backend available')
usb.core.NoBackendError: No backend available
When I run this script my NXT is plugged into my computer by USB and my NXT is on. Additionally, I have installed pyUSB (correctly, I think).
Why could this error be occurring?
The solution was to install libUSB. It seems the pyUSB library relies on libUSB in the background.
I installed libUSB with brew install libusb
Afterwards, that particular error was fixed.
Since my laptop crashed (for unknown reason) last night, Spyder has not been able to connect to a kernel. I am getting this error:
IOError: Could not find u'kernel-1809.json' in ['.', '~/Library/Jupyter/runtime']
(The name of the json file changes each time I attempt to launch an iPython console.)
This does not seem to be related to the matplotlib 1.5 issue, that I have seen elsewhere on here - it is using 1.4.3.
iPython (version 4.0.0) runs fine from the command line.

** Further update **
I deleted all files under the .spyder2/ folder in my user directory, reopened Spyder, and it was able to connect to an iPython console. So far, so good. Trouble is, when I added a path to the PYTHONPATH manager (so I could import external modules, such as nltk), I am back to getting the same error.
Had a similar issue and was able to resolve it by creating a new virtualenv with the same dependencies installed.
Now Spyder is working with the PYTHONPATH pointing at lib/python2.7/site-packages of the new environment.

My Firefox version: 26. I've installed Python 2.7. OS: Windows Vista, SDK: 1.14
The current 1.15 version of the Add-on SDK seems to be incomaptible with Python 2.7.6.
I got the same error and downgraded to Python 2.7.5 to solve this issue.
Here are some relevant bug reports:
Bug 950894 - [mozprocess] TypeError under windows evironment in cpython 2.7.6
Bug 958609 - Add-on SDK 1.15 incompatible with Python 2.7.6
Update: The bug has been fixed.
I suggest getting the latest version of the SDK (addon-sdk-1.15.zip) from the Mozilla Developer Hub :: Add-ons for Firefox web page. Also make sure to read an follow the instructions in the README file that comes with it (if you haven't already).
One pertinent thing it says is:
If you get an error when running cfx or have any other problems
getting started, see the "Troubleshooting" guide at:
https://addons.mozilla.org/en-US/developers/docs/sdk/latest/dev-guide/tutorials/troubleshooting.html
try to install add-on sdk 1.15 with python 2.6.6 then do this steps
1- Download cp720
2- unzip the zip file.
3- Copy or Move the file cp720.py into your python encodings folder.
Example: C:\Python26\Lib\encodings\
