Zsh: segmentation fault with Streamlit

Meena · July 28, 2024, 6:04pm

I followed the instructions here (Install Streamlit using command line - Streamlit Docs) & created a venv, installed streamlit, and tested the installation by running the streamlit hello example.

However, it exits abruptly with a zsh: segmentation fault.

Stack trace:

zsh: segmentation fault  streamlit hello

I noticed this happening especially when I navigate to other pages - Plotting Demo/Mapping Demo pages for example.
Streamlit version: 1.37.0
MacOS: Big Sur, 11.6

I have an earlier streamlit project from few months back which is in a different folder. That one still seems to be executing fine. Streamlit version: 1.31.1

Any pointers on how to resolve this? Would you recommend installing an earlier version of streamlit?
All these projects are running locally.

I am having the same issue on local appplications. I have tried multiple applications running version from 1.22.0 to 1.37.0 and I get “zsh: segmentation fault” on all attempts to run a streamlit application. The only application that works is ‘streamlit hello’ but that only works on 1.37.0. With the exception of “streamlit hello”, most version immediately terminate, while 1.37.0 will appear to connect but then show the "zsh: segmentation fault " after roughly 20 seconds of trying to connect.

I have destroyed and recreated environments nearly a dozen times (no exaggeration), restarted the machine. I am using conda virtual environments.

I went through the forums looking for answers and found 3 others on Big Sur who are experiencing the same segmentation fault problem, so this is unlikely a coincidence.

macOS Big Sur 11.5.2
Streamlit version 1.37.0

I am having the same issue "zsh: segmentation fault streamlit run… " I am using pipenv virtual environment. This is also on an older - (OK Ancient mid 2014 MBP) running Big Sur 11.7.10 at work. I run the same code on my home MBP M1 and it runs fine. My guess is the last update broke something on this old machine.

I am having the same issue - running Python 3.11 on an old Mac Mini running Catalina 10.15.7. I just set up a brand new environment and am running streamlit version 1.38.0.

I tested with Python 3.9 and 3.12 as well as testing with the previous poster’s streamlit version 1.31.1 and all of these combinations segfault as well, as soon as the page is loaded.

I can get the page to load with just streamlit, but then it misses matplotlib. When I install matplotlib, I then get the segfault.

Here’s the output with faulthandler enabled:

Fatal Python error: Segmentation fault

A reboot of the machine seems to have fixed this somehow.

I also installed streamlit from the micromamba environment creation command directly, i.e.:

micromamba env create -n myenv python=3.11 streamlit
