Run timing scripts from nx-parallel

[MridulS]

[Everyone can do this task. There is no need to claim/assign this issue]

In this task we will look at the https://github.com/networkx/nx-parallel repository which contains the parallel implementations for some NetworkX algorithms. The task for this issue is to generate a heat map file heatmap_betweenness_centrality_timing.png and upload to this repository.

• Clone https://github.com/networkx/nx-parallel locally.
• Run the timing script for betweenness_centrality using https://github.com/networkx/nx-parallel/blob/main/timing/timing_individual_function.py
  - $ python timing/timing_individual_function.py in the root directory of nx-parallel
• The script will generate a new file timing/heatmap_betweenness_centrality_timing.png

Add this file to your folder created in the first task and push the changes to github.

Create a pull request against this repository and add the file 2023-round-2/<your-github-username>/heatmap_betweenness_centrality_timing.png.

hi @MridulS sir, I am facing an issue with running timing/timing_individual_function.py script. I am getting a ModuleNotFound error for nx_parallel. I also tried creating a virtual environment but I'm still getting the same error.

Usually, when I create and activate virtual environments there is a __pycache__ folder in the Python modules. But, it's not getting created in the nx_parallel folder or any other folder. I checked using which python that my Python interpreter is also correct(the virtual environment one) and the environment is also getting activated. I cannot figure out what's the problem, please help.

Thank you :)

ModuleNotFoundError: No module named 'nx_parallel' i am facing the same error too

I also faced the same issue, but you can execute the file in the interpreter as such:
>>> exec(open('timing/timing_individual_function.py').read())
it should generate a heatmap file. To be sure, you can rm the existing .png files before running the command. Also make sure modules matplotlib, seaborn, networkx are installed($ python -m pip install packagename)

You need to install the package too. So after cloning nx-parallel, could you try running pip install . in the root directory?

Hello @MridulS

The Error ModuleNotFoundError: No module named 'nx_parallel' persists even after running pip install .. I used the solution described here and it generated the heat map file.

Try running PYTHONPATH=. python timing/timing_individual_function.py ?

This works thank you 🚀

Hello @akshayamadhuri,

The output you have indicates that your script is running correctly. Please wait for it to exit, and then check the output in the timing/ directory. The file name you should be looking out for is heatmap_betweenness_centrality_timing.png.

worked me for too, I checked the time the file was created, it was the time I ran PYTHONPATH=. python timing/timing_individual_function.py
