Data Analysis with Python Projects - Mean-Variance-Standard Deviation Calculator - Python

Tell us what’s happening:

Describe your issue in detail here.
I haven’t started the codes for this challenge yet. So, this post is not about doubts about the code to solve the challenge itself.
This looks like a problem with the set of files available on Github to be used in Replit.
I always follow the same procedure to start a project like this, as instructed. Start by importing the project on Replit; Next, you will see a .replit window; Select Use run command and click the Done button.
After that I hit Run to proper install / initiate the dependencies, such as Numpy.
In this project I’m receiving the following console error:

→ poetry lock –no-update
Resolving dependencies…

→ poetry install

Note: This error originates from the build backend, and is likely not a problem with poetry but with numpy (1.18.5) not supporting PEP 517 builds. You can verify this by running ‘pip wheel –use-pep517 “numpy (==1.18.5)”’.

I’ve tried several times to download again the repo from GitHub and star all over in Replit, but the result is always the same. I’ve tried a very basic code in the file mean_var_std.py

import numpy as np

a = np.array([1, 2, 3, 4])
print(a)

And the console returns what I’ve expected:

python3 mean_var_std.py
Traceback (most recent call last):
File “/home/runner/boilerplate-mean-variance-standard-deviation-calculator-3/mean_var_std.py”, line 1, in
import numpy as np
ModuleNotFoundError: No module named ‘numpy’

For me looks like some inste with the chosen version of NumPY to install. But I really don’t know what to do. Please somebody can help me with that? Maybe some crew member should be the better person to manage an issue like this.
Thanx!!
