Connection between smop and networkx - different errors depending on versions of networkx

I am new to python, and I found a matlab code online that I want to convert to python code using smop.
I've installed smop, however when I try to run it I get an error.
When I have networkx version 1.11 I get the following error trying to run smop main.m
Traceback (most recent call last):
File "C:\Users\IDABUK\Anaconda3\envs\smop\lib\site-packages\smop\main.py", line 66, in main
G = resolve.resolve(stmt_list)

u = G.node[n]["ident"]
AttributeError: 'DiGraph' object has no attribute 'node'
Errors: 1
When I install a later version of networkx (pip install networkx==2.0 or pip install networkx==2.5) I get the following error:

I am running this from the anaconda prompt window (anaconda power shell?).
Is there a way to fix this?
The only solutions I find online are people installing various networkx-versions which does not seem like a solution for me in this case, or changing 'node' to 'nodes' directly in the code, however I can't find any instances of 'nodes' in the matlab code.

For people in the future looking for an answer:
I could not find an answer for this.
However it worked using matlab2python.
This is how it worked for me:
In the terminal I wrote
git clone https://github.com/ebranlard/matlab2python
cd matlab2python
pip install -r requirements.txt
and then I used this code to convert each matlab-script:
python matlab2python/matlab2python.py file.m -o file.py

My pip is broken on Windows, how can I fix it?

Whenever I try to use pip, using any command I get this:

I am on Windows 10, 64 bit, Python version 3.7.7.
I cannot use pip, how can I fix it?

If pip is broken after an attempted upgrade to a newer version, try the following:
Download get-pip.py and "Save As" the file using right-click.
Open a command prompt as an administrator
cd to the path where you saved the file, in my case
cd C:\Users\xyz\Downloads> then type python get-pip.py. It will install all required packages, such as wheel and pip.
To check if it installed correctly, type pip --version in the command line.
Hope my answer helps someone. Happy coding. 🙂

Try doing python -m pip install pytest. This should install it, and it will make it usable by your IDE.
Hope this helps!

You could follow the equivalent steps mentioned here and here (Both are closed issues on pip's github page) on your windows machine.
On windows you can do this:
python -m pip uninstall pip setuptools # Sometimes setuptools might be the problem
This will uninstall pip and setuptools.
After which you can reinstall them using
python -m ensurepip
This will install pip and setuptools.
I have tried this on my windows 10 machine running Python 3.7.4!

I am unable to download anything using "pip" function

When I try to install any module for python using command prompt or PowerShell, then there is a message that shows up, the message is:

I know it has the names of my drivers and all. Due to this, I am not able to download any module for python.
Things that I have tried and that failed me:
I Googled it
YouTube videos were not tackling my problem, what they were telling me is just how to install pip (which I already have) and how to add the path (which I have already done)
Commands that gave this error:
pip install flask
py -m ( I don't remember it fully but i wrote it correctly )
pip3 install flask
and i have also uninstalled and installed python
etc.
Here is my error message in the command prompt:
I also tried that py -m statement but that also gave the same result.

You can try to re-install pip or even completely re-install Python.

Add matplotlib package to python shipped with 3rd party software?

Let me begin by saying I am very new to python so I will try to be as concise as possible, but please read my question with that thought in mind and have mercy on my ignorant soul.
I am working with an application, written in C++, that ships with Python version 3.4. The software allows users to write Python scripts and save them to a directory in order to control the program through these custom scripts. However, the Python library that ships with the software doesn't include matplotlib. Is it possible to use the pip installer to install matplotlib in this program's Python directory? I tried using --target with the pip installer, but that has not worked for me. If I cannot use pip, can anyone direct me to some documentation that might help me understand how to add packages to Python shipped within another program?
Furthermore, for future reference, is it possible to upgrade the version of Python within this program to Python 3.7 without access to the program's C++ source code?
Thank you for any input and help, and for not spitefully bashing my poorly posited question.

Windows, Python27 ImportError: cannot import name IncompleteRead

I have read many of the questions and answers regarding "IncompleteRead" most, if not all, of them end up with a recommendation to uninstall and reinstall pip, or upgrade pip, or uninstall and reinstall the package you are trying to install.
I am not able to even upgrade pip or uninstall it.
Here is the traceback:

Any suggestions?

You can try and remove requests module first dist-packages
rm -rf python2.7/dist-packages/requests*
pip module need requests module to download packages from Python Package Index.
Hope this might help

I suggest you download the package yourself from here or find it yourself, and then try pip install urllib3-1.25.7-py2.py3-none-any.whl (replace the filename with the wheel you download). This way, you can reinstall urllib3 without importing it first.
