AttributeError: module 'matplotlib' has no attribute 'axes'


I am trying to run the same st.pyplot code and get this error: AttributeError: module ‘matplotlib’ has no attribute ‘axes’.

Steps to reproduce

Code snippet:
import streamlit
import numpy as np
import matplotlib.pyplot as plt
arr = np.random.normal(1, 1, size=100)
fig, ax = plt.subplots()
ax.hist(arr, bins=20)

I have matplotlib v3.7.2 installed

Expected behavior:

the chart should render

Actual behavior:

    fig, ax = plt.subplots()

Hey @Matt_Burd,

Thanks for sharing your question!

Have you imported streamlit in your app? Your code snippet excludes that import, and your app does run without errors for me once I add that line.

yes, I neglected to show that. Streamlit is working apart from that plotting issue

I just got a similar error with completely different packages (ndx-sound). I think it might be a version control issue, so if you end up finding a solution, I’d be happy to hear what it was!
Haven’t found the error message anywhere else online…
