Sea Level Predictor: Can not run. problem of installation?

Question:
project: Sea Level Predictor
problem :
have not write any code yet.
have installed pandas, matplotlib, scipy
When I run, system display following message.
Question:
Is there any problem in installation?
Or I can just ignore the message and go ahead to key in code to finish the project?

code snippet

import pandas as pd
import matplotlib.pyplot as plt
from scipy.stats import linregress

def draw_plot():
    # Read data from file
    # Create scatter plot
    # Create first line of best fit
    # Create second line of best fit
    # Add labels and title
    # Save plot and return data for testing (DO NOT MODIFY)
    plt.savefig('sea_level_plot.png')
    return plt.gca()

The current project's Python requirement (>=3.8,<4.0) is not compatible with some of the required packages Python requirement:
  - numpy requires Python >=3.9, so it will not be satisfied for Python >=3.8,<3.9

Because no versions of numpy match >1.26.2,<2.0.0
 and numpy (1.26.2) requires Python >=3.9, numpy is forbidden.
So, because root depends on numpy (^1.26.2), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For numpy, a possible solution would be to set the `python` property to ">=3.9,<4.0"

    https://python-poetry.org/docs/dependency-specification/#python-restricted-dependencies,
    https://python-poetry.org/docs/dependency-specification/#using-environment-markers
exit status 1

Go into the file named pyproject.toml
There is a line that says:

python = ">=3.8,<4.0"

or something similar.
Change it to

python = ">=3.9,<4.0"

That is what the error message said to do.

For numpy, a possible solution would be to set the python property to “>=3.9,<4.0”

thanks for your quick reply.
I change from python = “^3.8” to python = “>=3.9,<4.0”
But When I RUN, system display a lot of message.

I uninstall pandas, matplotlib, scipy and numpy. And install them again.
It still display a lot message.
part of the message :

copying pandas/tests/arrays/sparse/init.py → build/lib.linux-x86_64-cpython-310/pandas/tests/arrays/sparse

It seems always do upgrading each time when I RUN.
What is the problem now?

Set your pyproject.toml file to this:

[tool.poetry]
authors = ["Your Name <you@example.com>"]
name = "root"
version = "0.0.0"
description = ""

[tool.poetry.dependencies]
python = ">=3.9,<4.0"

Then run your code. It will automatically install everything for you. Then, it shouldn’t take long to run your code after that.

Maybe try entering the lines:

disableGuessImports = true
disableInstallBeforeRun = true

In the .replit file, after the entrypoint line?
