"No Module named: yfinance error", Included requirments.txt file

Community Cloud

When I try to deploy my app to streamlit cloud, I’m getting the no module error.

Link: GitHub - IanP07/StockChecker: Simple Stock Checker app hosted on streamlit

There are only 2 files in my project, the main.py file and the requirments.txt file. for the requirements file, I just got the latest version of each of the modules and pasted it in, as of right now it looks like this:

yfinance==0.2.4
streamlit==1.34.0
plotly.express=0.4.1

Here is the full error message:

ModuleNotFoundError: No module named ‘yfinance’

Any help would be much appreciated, thanks!

Welcome to the community, @I_N_P! :hugs:

I believe plotly.express should be part of the plotly package. Update your requirements.txt to:

yfinance==0.2.4
streamlit==1.34.0
plotly==5.5.0

Re-deploy your app with this updated file. Hopefully, it will resolve the ModuleNotFoundError.

Let me know how it goes!

Best,
Charly

Hi Charly, thanks for the response.

Reading through my code I realized that I had misspelled the requirements.txt file, to ‘requirments.txt’. I even did it in the title of this post haha.

It’s loading now, but weirdly, when I try to input a valid date, I get an error, and no graph shows up. It still works when I run it locally, but not deployed. Here’s the full error:

Not sure why this error is occuring, the error message that pops up on screen is:

Code all seems to be matching, the only thing I can think of is that there was a .devcontainer folder added to the github repo automatically, but I didn’t want to delete it incase it’s necessary and not causing the error

Also, not sure if this is necessary to add, but the program does work in streamlits built-in codespace editor.

Yeah just checked it again and still not displaying any graphs for whatever reason, the main issue seems to be

“Cannot accept list of column references or list of columns for both x and y”

But it works when run locally. is it an issue with downloading a module perhaps?

What if you show the data instead of plotting? Is it what you expect?
