Yaml with Python 3 - python-3.x

I have a python3.6 virtual environment. I an trying to run some keras code and came across this error:
Traceback (most recent call last):
File "test.py", line 4, in <module>
from keras import backend as K
File "Keras-2.0.8/keras/__init__.py", line 4, in <module>

import yaml
File "Keras-2.0.8/yaml/__init__.py", line 2, in <module>
from error import *
ModuleNotFoundError: No module named 'error'
I saw a few other posts regarding this but those all suggest that the problems may be that I am using the python 2.7 version for python3. However, I don not think this is the case since I am in a python 3.6 virtual environment.
I also saw some comments about re-installing/upgrading yaml with python3.6 specifically. I thought doing a pip install in the virtual environment would fix this but it did not seem to help. Any suggestions regarding how to resolve this issue would be much appreciated.
Side Note: the code I am trying to run is test.py from this repo when I come across the error.

ModuleNotFoundError: No module named 'six' - python 3.8.5

When trying to open jupyter notebook from my terminal in Visual Studio Code, I keep getting the error below. I have tried uninstalling and reinstalling six using conda install but the same issue persists. It was working fine yesterday so I don't know what happened between now and then. I'm using Python 3.8.5 in my virtual environment. Any ideas what could be the issue?

I had the same issue, six was showing as installed by conda and loading fine when imported manually in python. The base version of Jupyter Notebook would load, but Jupyter Notebook wouldn't load in my virtual environment.
Running pip3 install six from a terminal with my environment activated seemed to solve the issue but I don't know why!
Also make sure the path to Conda in the VS Python extension settings is correct.

distutils.util missing after upgrading to 3.8

I just upgraded to Pop OS(Ubuntu) 20.04, which upgraded Python 3.7 to 3.8. Now I get this error below when I run sam (from the AWS SAM CLI). Solutions found online all had to do with making sure python3-distutils is installed. I have verified that python3-disutils is installed. /usr/lib/python3.8/distutils looks fine, just not getting picked up for some reason.
One thing I noticed is that in the traceback below, it's using the system-wide pip, while I have a later version of pip installed under my .local. I don't know if those two symptoms are related but looks like I'm missing some config somewhere so none of the 3.8 or user space stuff is picked up.

I have the same issue on Debian Bullseye (or rather mixed Bullseye/Buster).
Package python3-distutils (3.8.6) contains module for Python 3.8 and 3.9 (!).
Old package (3.7.3) for Python 3.7. You have to choose.
My workaround is just copy module.
mkdir -p /usr/lib/python3.7/distutils
cp -a /usr/lib/python3.8/distutils/* /usr/lib/python3.7/distutils/

Can not import Spacy : ImportError: preshed.maps does not export expected C function map_clear [duplicate]

ImportError: preshed.maps does not export expected C function map_clear
I updated conda and then run update conda all. I removed the previous version of python and installed the newest one (3.8). I uninstalled spacy and reinstalled it. Nothing worked.
The last time I worked with spacy was 3 weeks ago and I did not face any problem. All of a sudden this exception erupted out of nowhere.
What is your understanding of the situation? Any ideas on how to debug the problem or remedy the failure?
I had the same issue, I fixed it by re-installing preshed with the --upgrade flag.

unable to run a python file because of Module not found error despite sourcing the pythonpath

I have been trying to run a python file using rosrun command but unfortunately I am having this module not found error because of a package named rospkg. Until a day before yesterday, it was all working fine but yesterday, ubuntu18.04 has got some updates out of which an update for ubuntu base was also present, since that update I am having this error.
I have tried to check whether I have installed the respective python-rospkg and its says I already have the latest version. I have also using
echo $PYTHONPATH
to check the sourced paths and they are sourced correct, I am not sure whats causing this error.
the error is as follows
Traceback (most recent call last

The shebang for my is as follows,
#!/usr/bin/python3
When i try to run the file by changing the shebang to
#!/usr/bin/python2.7
I get the following error
Traceback (most recent call last):

I have installed tensorflow version 1.14 using pip installation. Can anyone please help me solving this error. Thanks in advance
edit:
I have manually tried to set the python path to /usr/lib/python2.7/dist-packages as when I tried to install python-rospkg, it says the its already instaled in that location. Doing that I am having error importing tensorflow and the error is

python3 path only running google-appengine modules

The file usr/local/google-cloud-sdk/platform/google_appengine/lib/distutils/distutils/command/install.py has lines like this and is compatible with python 2.1. Note. this is not the official google repository but it's accurate:
print "config vars:"
This means that install.py is a python 2 file and you are running pip from python 3. There probably is some incompatibility between them.
