Matplotlib version 3.3.0 causes ft2font DLL ImportError - matplotlib

I recently upgraded matplotlib from version 3.2.2 to 3.3.1. When I tried to import matplotlib I got the following error message:
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "E:\SWIM\test\venv\lib\site-packages\matplotlib\__init__.py", line 174, in <module>
_check_versions()
File "E:\SWIM\test\venv\lib\site-packages\matplotlib\__init__.py", line 159, in _check_versions
from . import ft2font
ImportError: DLL load failed: The specified module could not be found.
When googling for answers, most of them recommended downgrading matplotlib. But the results were many years old, and I don't feel like downgrading. I want the latest version to just work.

Turns out I had Microsoft Visual C++ 2008 Redistributable installed, and I didn't have any newer version. By installing the latest 2015-2019 edition, my problem was solved (Downloads can be found here).

I figured it out.
If you have already installed matplotlib, but the error still comes about. Then you have to download Microsoft C++ from their website.
https://www.microsoft.com/en-US/Download/confirmation.aspx?id=48145
install Microsoft c++ then you can try again to run your code.
it has worked for me like magic.
I got the solution from a youtube video.

Cannot import sentinelsat python module

I am a python newbie and am trying to get the sentinelhub module to work but have been receving this error message on my code:
import sentinelhub
Traceback (most recent call last):
File "<pyshell#0>", line 1, in
import sentinelhub
ImportError: No module named sentinelhub
After I've downloaded the module using "pip install sentinelhub" on the windows command. I am currently using Python version 2.7.18. Any suggestions would be helpful. Thanks.
It looks like sentinelhub requires a different version of Python.
From their own website they specify that it "requires Python >=3.7"

cannot import name 'nosetester' error while importing pandas

Im getting below error while importing pandas
cannot import name 'nosetester'
Traceback (most recent call last):

ImportError: cannot import name 'nosetester'
Pandas version ->0.18.1
Numpy version ->1.18.0
Any help to resolve the error?
One approach is to use python 3.6 version like 3.6.5 is a stable version.
Another approach is if you want to continue in python 3.5 version itself then python 3.5.2 it worked correctly.

beautifulSoup 4 works on python2.6?

I'm trying to do a web scraping project using bs4, but on the remote server they have python 2.6.6 installed.
Can I work with bs4 on python2.6.6?
I already tried but got these errors:
Traceback (most recent call last):

ver = "{}.{}.{}".format(self.major, self.minor, self.micro)
ValueError: zero length field name in format
I am the author of the failing dependency soupsieve, and can verify that soupsieve does not support Python 2.6.
It is possible that that an earlier version of Beautiful Soup (before 4.7) does fully support Python 2.6, but I'm not sure.
Python 2.6 is such an old version that even the Python team has stopped supporting it.
You could try installing older versions of Beautiful Soup and see if one of them allow you to move forward, but I can confirm that the latest versions, at least 4.7 and above, will not work on Python 2.6.

cannot import name PyMCObjects when import pymc

I have pymc installed, and I am now trying to import it in my code. However,
First when I do import pymc, I got the error message:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "//anaconda/lib/python2.7/site-packages/pymc-2.3.3-py2.7-macosx-10.9-x86_64.egg/pymc/__init__.py", line 30, in <module>

from . import flib
ImportError: numpy.core.multiarray failed to import
which can be fixed by manually import numpy.core.multiarray, but then, when I try again to import pymc, I got another error message:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "//anaconda/lib/python2.7/site-packages/pymc-2.3.3-py2.7-macosx-10.9-x86_64.egg/pymc/__init__.py", line 30, in <module>

from . import PyMCObjects as pm
ImportError: cannot import name PyMCObjects
I googled around, and the solutions to similar problems are either:
In case that's related to the installation of pymc, force using the 32-bit instead of 64. However, this answer is for Windows users, and I have OS X 10.9 (Mavericks).
In other cases, it's usually due to a circular dependency (for example, here), which I don't think is the case here.
My guess is that something is wrong with the package flib, but I couldn't figure out what. I would appreciate any answer/hint on this problem. Thanks in advance!
Update (July-4-2014)
Thanks, Chris! I rebuilt my pymc using the conda build by doing conda install -c https://conda.binstar.org/tobeplugged pymc, and now when I do import pymc, a different error message appears:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "//anaconda/lib/python2.7/site-packages/pymc-2.3.3-py2.7-macosx-10.9-x86_64.egg/pymc/__init__.py", line 44, in <module>
from . import CommonDeterministics
ImportError: cannot import name CommonDeterministics
As Chris pointed out (see comments below), the problem(s) is being looked at here. The problem seems to have to do with the version of gcc (version 4.9). I will try to rebuild my gcc with the older version (4.8.2) later today to see if that will solve the problem for OS X 10.9 (Mavericks). Otherwise, I believe people can wait a little bit for the pymc team to solve this problem, too.
