- My app wonāt open. Source: https://share.streamlit.io/steveschneider2/pass/main/TrafficStreamlitApp.py The app (python) needs to load a āpickleā file (which is a ML Model). I have t his app running well on my machine. Today was the first time i have connected to the streamlit cloud. The pickle file is in the same folder as the python file, and is in the Github repo from which the app loaded. So, if the pickle file was loaded (as just one of the files in the repo) āupā to streamlit why can it not be located? Should i be changing the load line somehow? Below is that line: xgb1 = pickle.load(open(āFloridaTraffic2014xgb.pklā, ārbā)) Any help is appreciated. If i am asking this question in the wrong place, please re-direct me. Thanks! also, hereās the error msg: File ā/app/pass/TrafficStreamlitApp.pyā, line 57, in xgb1 = pickle.load(open(āFloridaTraffic2014xgb.pklā, ārbā)) (edited)
Hi @steve_Schneider , welcome to the Streamlit community!
Can you post more of the error message, itās not clear what the issue might be. You could also try setting the Python version on Streamlit Cloud; pickle requires that you use the same Python version to read the pickle as was used to write it:
Best,

randy, first, thank you for your response. Second, i deleted the app, reloaded, specifying Python 3.8. Here is the key part of the messagingā¦

So it looks like the issue isnāt actually the pickle, but that you are missing a dependency in your requirements file. Which in your case doesnāt actually exist.
Create a file named requirements.txt
, and place the packages you need to install into that. If you install pipreqs LOCALLY, you can generate the requirements.txt
file you need. Commit that to your GitHub repo and you should be all set.
Best,
Randy
Randy, thanks much for your assistance. It is now up and running. Have a GREAT day!
