Hi everyone, I’m trying to deploy a very trivial dashboard and I always get this error.
import pandas as pd
import numpy as np
from matplotlib import pyplot as plt
import scipy.stats
import streamlit as st
and the requirements.txt that I tried where:
scipy
matplotlib
numpy
pandas
streamlit
scipy.stats
matplotlib.pyplot
numpy
pandas
streamlit
and this with the corresponding version numbers
scipy==123
matplotlib==123
numpy==123
pandas==123
streamlit==123
Where’s my mistake?

Hi @LeonardoAcquaroli
The error results from a combination of having spaces in the directory name and using the incorrect syntax in your requirements file.
The steps to resolve your issue:
Rename the Project 5 - States data folder to not have spaces. Something like Project-5-States-data. Replace the empty spaces with -.
Fix the errors in your requirements file. The package is scipy, not scipy.stats . The package is matplotlib, not matplotlib.pyplot .
Once you make the above changes, and deploy your app, it should install the requirements:
You will run into other errors unrelated to this thread. Namely, your script tries to load files from non-existent directories. You will have to change those filepaths in your code to
states = pd.read_excel(r"Project-5-States-data/State data.xlsx")
After which you will run into another error about a missing openpyxl dependency required to read Excel files with Pandas. So you will also have to include openpyxl in requirements.txt:
scipy
matplotlib
numpy
pandas
streamlit
openpyxl
Doing all of the above will finally lead to a successful deploy:
