I have the Anaconda distribution of Python 2.7 and I needed to install the Jupyter notebook package. During the installation process my computer turned off and after that I couldn't continue with the process. I tried to uninstall Jupyter and try installing it again, but I keep getting the same error:

What should I remove/add in order to make it work?
You need to install the python package simplegeneric. After you install it, you need to install the next package that you fail to import. Continue this process until you dont get any import errors.

I am trying to run a program (obviously written in python) and it requires some python modules. One of the missed modules is aiomultiprocess. I tried installing it with pip install aiomultiprocess pip3 install aiomultiprocess python3.7 -m pip install aiomultiprocess but they all come back with the same error message:

ModuleNotFoundError: No module named 'ffi'
No ffi module?! Let's get it!
I looked it up and figured it's a foreign library that come, in the case of python, as 2 forms: CFFI & LibFFI, but "ffi" doesn't exist for python. I installed cffi libffi and added them to this path /usr/local/lib/python3.7/site-packages/, but it changed nothing.
So my question is there another way to install python modules without the need of pip??!
I'm trying to use mayavi in python to visualize a pointcloud, and cannot resolve this error. I'm sure it is an easy pip install, but I am unsure of the command. Any help is much appreciated! Thanks!
BTW, I am running Ubuntu 18.04 and have tried installing scipy as mentioned here: Python import error "getfullargspec". I have also ran pip install traitsui. Additionally, I have rebooted my system.
Update:
After further digging, it appears that it may be an issue with Python versions. I was able to get it to run with Python3, but not Python 2.7 (I need it to work with python 2). I have also tried modifying the code within handler.py to getargspec instead of getfullargspec. I was given an error about trait_factory by doing this
Here is the entire printout:

The solution for this problem was to use older packages. Not all of the dependencies such as traitsui are compatible with Python 2.7. Even though an older version of mayavi was installed, the dependencies that are installed automatically are not compatible (they only support Python 3).
Here are the versions that work well together for me:
mayavi==4.6.2
traitsui==6.1.3
traits==5.2.0
numpy==1.17.4
pyface==6.1.2
To install a specific version, just run sudo pip install packageName==#.#.#
An import error occurs when trying to run jupyter notebook
I'm trying to run jupyter notebook using anaconda (git bash platform), and as I type in jupyter notebook, an import error occurs every time. I tried to lauch it inside an environment, but the same error occured.

After reinstalling pyzmq (and I tried reinstalling conda too), the following error occurs:

I found a similar issue open on GitHub for zmq. The recommendation by GitHub user harsh23tyagi that seems to work for most is to run the following:
pip uninstall pyzmq
pip install pyzmq
Working with conda env, jupyter notebook worked in (base) env but gave the .libzmq error in (my_env).
To be able to run notebooks from my_env, this worked for me :
pip uninstall pyzmq
pip install pyzmq==20 (no version for pyzmq didn't fix the issue for me)
It seems that updating pyzmq to the latest version fixes this problem for me.
conda install pyzmq=22
I've installed xxhash module with:
sudo pip install --upgrade pip
sudo pip install xxhash
But when I execute:
pydoc modules
I get a list of available modules in which there's no xxhash.
And when I run in terminal a GUI program it gives me an error:

BTW, the 2 first commands worked with no error and when I rerun them it says that these modules are already installed and up to date.
Here is my error:

openpyxl module has 2 dependent modules : 1. jdcal 2. et_xmlfile
I was able to install openpyxl module and this is what I did :
1.Downloaded the openpyxl,jdcal and et_xmlfile from https://pypi.python.org/pypi and saved jdcal-1.0.tar.gz, et_xmlfile-1.0.0.tar.gz,openpyxl-2.3.0-b2.tar.gz in a local folder in my system.
2.Then I ran the commands in the following order :
pip install jdcal-1.0.tar.gz
pip install et_xmlfile-1.0.0.tar.gz
pip install openpyxl-2.3.0-b2.tar.gz
openpyxl got successfully after this. Please check whether this helps.
