I have been trying to code the display on my Ableton push 2 with python using this guide: github.com/ffont/push2-python#using-the-simulator, but I ran into a problem with pyusb and i was missing libusb. pip3 kept saying I already had it installed but I still kept getting errors when trying to use Libusb. So i tried using homebrew and it installed it but I still keep getting errors when using libusb.
this is what my terminal looks like when trying to import:
>>> import libusb

I have made a few projects which run fine. A new project required me to install pip install cbpro (a module for dealing with coinbase cryptocurrency API).
After installing it, even running the simplest code throws several errors:
Input:
import cbpro
import pandas as pd
c = cbpro.PublicClient()
data = pd.DataFrame(c.get_products())
data.tail().T
Errors:

Secondly, when I then go to other projects that were working well, I get additional errors. Of note, those projects start with:
import pandas as pd
import requests
import json
Errors:

Things I've tried:
If I uninstall cbpro, then uninstall and reinstall requests, I can undo the error and am back where I started. However, I'm interested in knowing why I am encountering these errors because I'd like to actually use cbpro and know how to solve this issue in the future.
The libraries I was using were not compatible with Python 3.10. I am still at a loss for how I would inherently know that based on the errors thrown, but since then my solution was to install Python 3.9 and see if I still get the same errors when running 3.9.
(Then I also read that it might be a better idea for my current purposes to use a slightly older version of Python, so I moved over to 3.9 completely and haven't had the same issue again.)
I've installed BSON library to convert strings to MongoDB ObjectIds, but when I try using the library, this comes up:

Also pip installs py3compat, but there's no 'binary_type' in there.
Any idea how to fix this?
I saw this error and got it fixed by installing the newest version of pymongo.
(at the time of writing)
pip install pymongo==3.5.1
I'm using terminal on mac, and anytime I attempt to use pip, I get the following error message telling me that it cannot find a module named zlib:

ModuleNotFoundError: No module named 'zlib'
I've read several SO posts with the same error message, and have tried their solutions, including attempting to install zlib using homebrew, which fails, and updating my Xcode developer tools. I also installed pip earlier using python get-pip.py, and it said it installed successfully.
The reason I need pip is to install a package for use on python 2.7, but doing $ pip install "package-name" produces the same error as above. I have both Python 2 and 3 installed on my machine, if that helps. I'm kind of new to pip and using the command line in general, and I'm super confused; if anyone could help me out I'd really appreciate it.
This is the OP. I was able to fix the issue, and wanted to post my solution here in case it would help others.
Essentially I believe it occurred because Python2 is default on my machine, but pip is by default pointing to resources pertaining to Python3, or something like that. Doing pip2 --version instead provided the expected response.
I am trying to run some C++ code with embedded Python. Code was working completely fine a couple of weeks ago. The code still compiles, but I am now getting the error

Since then the only change I have made is to install the macOS Supplemental Update and to upgrade Python from 2.7.13_1 to 2.7.14_2 (using Homebrew). I have changed the relevant linker flags in the makefile, i.e. those that appear when I type python-config --ldflags. I have also made sure that the Python I am using is definitely the Homebrew one by inserting export PATH="/usr/local/opt/python/libexec/bin:$PATH" into my .bash_profile as directed by Homebrew.
I am not sure whether this error is because of the Python update, the recent macOS Supplemental Update, or something else. Any idea what the problem could be?
Thanks
I had the same problem;
In python 2.7 the NumPy 1.8.0 was available,
Then I installed NumPy (again) using brew, and it wasn't available in my python (2.7) anymore. (Got the same error you got here)
So I did "brew unlink python && brew link python" to use python 3 (instead of 2) which NumPy 1.14 is available in it.
I guess the python 2.7 was not compatible with this recent version of NumPy.
I want to use the module autobahn-autoreconnect and it works fine locally with PyCharm. I just install the module with PyCharm and exchange the old ApplicationRunner line with the new one:
# from autobahn.asyncio.wamp import ApplicationRunner
from autobahn_autoreconnect import ApplicationRunner
But when I install it on an Ubuntu server with pip3 install autobahn-autoreconnect and then use just import autobahn_autoreconnect I get the following error:

What am I doing wrong?
The following solution worked for me.
First:
import txaio
txaio.use_asyncio()
Second:
from autobahn_autoreconnect import ApplicationRunner
