Hi guys, I am having problems with serving my app in a browser. I deployed it successfully with Heroku CLI but keep getting the message below on my browser. Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs …

The problem is that streamlit is not installed on heroku, hence you get bash: streamlit: command not found. this is easy to spot (and pretty much the way you debug all such traces): you find the interesting stuff between the general heroku app logs and the low-level error messages. My spidey senses…

Hi @maxpumperla thanks again for your time. Actually i do have streamlit on my requirements.txt. streamlit==0.57.3 All the files are here: [image] bruno154/Data_Science_Python Repositorio voltado a trabalhos em data science utilizando a linguagem python. - bruno154/Data_Science_Python …

scikit-learn has scipy as dependency, which doesn’t work on heroku without extra work. install a build pack for your project like so: heroku config:set BUILDPACK_URL=https://github.com/andrewychoi/heroku-buildpack-scipy.git Also, you might just want to slim down your reqs, this is enough: streaml…

Hi, there’s no error with the scikit-learn @bruno154 @maxpumperla . I did it with the following guideline here [image] How to Deploy Streamlit on Heroku For Endless Possibilities in Data Science Reading time: 5 min read just take note for the setup.sh y…

@bruno154 I suggest that you deploy a ‘Hello World’ before you dive deep on your wine classifier. You can use my files as a reference less Docker [image] Anyone able to deploy to heroku using docker? 🚀 Deployment Hi alll, i was able to deploy via AWS(docker) and heroku …

@Andrew_Ng , i will check your files but i already have others apps deployed even more complex than this one(code wise at least). I just cant understand what is going wrong here, maybe something related to the pickle that i use to load the model. Well, thanks for help me.

I think pickle should be fine since it’s based on python if jobslib it’s more sensitive, scikit-learn version need to be similar. versioning window for scikit is smaller than pickle.

I’m having the same issue as @bruno154 : [Screenshot 2020-08-19 at 16.27.19] I’ve included Streamlit in my reqs and my setup.sh file is the same as @Andrew_Ng I am a Junior Data Scientist trying to gain some skills in the Machine Learning Engineering field so Developer and Stack knowledge are tha…

UPDATE: removing the Pipfile/Pipfile.lock and just leaving the requirements.txt solved my issue. I’m having problems with the XGBoostRegressor but that’s a different issue :laughing:. Hope this helps!
