This is a console command. It looks like you have typed it into a Python interpreter. What happens if you type it at the command line? – Kerianne

I show in cmd 'streamlit hello 'streamlit' is not recognized as an internal or external command, operable program or batch file.' – Hipolitohipp

That is because the instructions on the Getting Started page are for Linux and you want to run it under Windows. Windows will not look for a shebang inside the file to discover how to run it. It has to be told. Try python.exe path_to_streamlit\streamlit.py. If you get the same error message then Windows also needs to be told where your Python interpreter is. Something like C:...\python37\python.exe. – Kerianne

I slow this issue using upgrading steamlit and the previous version of NumPy – Hipolitohipp

Actually it looks like you have misunderstood in where you have to use streamlit hello. This command will bring you to the welcome page of streamlit if you have successfully installed streamlit. I assume that you are a beginner. This streamlit hello should be entered in command prompt, But not in the Ipython Kernel. But you have entered this command into the Ipython Kernel. Look at this to learn how to use streamlit hello and how to run a python script with streamlit.

Answer 7

Try and run it through the command prompt (anaconda prompt). If it tells you that 'streamlit' command cannot be recognised and you are sure you have installed streamlit to your environment, then add Anaconda folder into your Windows path. To do this, go to Advanced System Setting -> Advanced tab -> Environment Variables, under 'System Variables' -> Path -> Edit -> New, then copy the path to your Anaconda folder, e.g 'C:\ProgramData\Anaconda3' and click OK all through. That should work. If it does not, visit https://discuss.streamlit.io

Create a virtual environment in your folder or repo with this command

Activate the venv (virtual evnironment) that you created with

Windows command prompt

$ .venv\Scripts\activate.bat

Windows PowerShell

$ .venv\Scripts\Activate.ps1

$ source .venv/bin/activate

Run your Streamlit app using command

$ streamlit run "Name of file".py

If it doesn't work try this:

$ python -m streamlit run "Name of file".py
