I have found a package in GitHub which can clearly tell the time complexity of a python code, The link for the package that I have found in GitHub is here. I tried installing it in my PC using "pip install time_complexity_estimator" but I ended up with some errors.

Someone please tell me how to install it.

The reply from my command prompt is follows :

  DEPRECATION: scipy is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

      with pip instead of using `setup.py install`:

        - `pip install scipy`   (last SciPy release on PyPI)

  • Those versions of numpy and scipy are *really* old, and your system failed to compile them for the reasons shown. That means the module you're trying to install hasn't been maintained in years, and may not work even if its requirements were updated. – MattDMo Mar 15 '23 at 17:38

  • I get it sir, Is there any possibilities to get it now ? – 042 Sanjaykumar Mar 16 '23 at 00:40

Welcome to stack overflow!

I think this is a bug on the developer's end, not yours. I tried running it and I got the same result. I also tried cloning the repository manually and using the setup.py file, but that also threw me an error.

I've posted an issue on the repository to alert the developer's that this is happening. I recommend you do the same, since it might grab more attention. Otherwise, I'm not sure what to suggest. I apologize if this isn't the answer you're looking for!

Edit: this is what I got, and based on our similar experiences, I think that it is an issue on our end. It could not be, it might just be a coincidence, so I'd also ask a friend to see if they can install the module.
