Hey @Cellule_Boukham :wave:,

If I’m reading your screenshot correctly, this looks like a Python environment issue, where for some reason the streamlit executable is not in your $PATH. Can you post a few pieces of data to help debug?

  1. How exactly did you install Streamlit?

    • pip install streamlit
    • pip3 install streamlit
    • sudo pip install streamlit
    • pip install streamlit --user
    • Something else?

  2. Can you post the output of these commands?

    $ echo $PATH
    $ which python
    $ which streamlit
  1. What do you get when you try this:
    $ python    # (or python3 if you used pip3)
    >>> import streamlit
    >>> streamlit.__file__

Hi, I have the same issue, I’ll be glad for any advice. I’m using conda for env managment. To answer your questions above:

  1. I’ve installed it using pip3 (however I tried using pip before)
  2. echo $PATH
    /home/eliska/anaconda3/envs/deepnet-2-gpu-gui/bin:/home/eliska/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

$ which python
/home/eliska/anaconda3/envs/deepnet-2-gpu-gui/bin/python

$ which streamlit
(nothing)

  1. returns:
    ‘/home/eliska/.local/lib/python3.6/site-packages/streamlit/init.py’

Hi @emal

From the data you posted, my guess is that when you pip-installed Streamlit you weren’t inside your Conda environment. I say this because your Streamlit was installed in ~/.local/lib/... rather than in ~/anaconda3/envs/....

So try this:

# Remove Streamlit from your local Python installation.
conda deactivate
pip uninstall streamlit

# Activate the Conda environment and install Streamlit.
conda activate envName  # Replace with the name of your environment
pip install streamlit

Hi, thanks for the effort @thiago. That would be a logical assumption. However, when installing streamlit I was already in the environment, that’s why I’m not sure why it gets installed outside. But after your comment, at least I know it should work this way, so I’ll try to fix it somehow.

Hi thiago, I have the same issue, I’ll be glad for any advice. I’m using Python 3.7. To answer your questions above:
1 I’ve installed it using " pip install streamlit "
2 echo $PATH
/media/felipe/SAMSUNG/LAPTOP RECENTE/felipe/Python3.7/Semana de Data Science/aula03/aula03

               which python:
               /home/felipe/miniconda3/bin/python

                which streamlit
                (NOTHING)

          3.returns
            Python 3.7.1 (default, Dec 14 2018, 19:28:38)

import streamlit
streamlit.file

That’s it. As I see, I managed to install streamlit both in my /home address and in the $PATH written above, but unfortunately the “streamlit” command has not been found. How can I solve this problem?

Experienced the same problem. I got it to work by adding

export PATH="$HOME/.local/bin:$PATH"

to my .zprofile

@Roberto this solve my same issue, but temporarily means once I close the terminal, after reopen I need to do the same. Can U plz explain in detail how to get a permanent solution. Thanks

9

Oh right source /.zprofile after adding the export line

10

Thanks but not working. :frowning_face:

11

Thank you!! This worked

12

Nevermind… this was not the right thing to do. This gave me even more issues, I had to fix with someone more knowledgable than myself later on… Do not follow this advice!!!

13

Hey I had the same issue. If you are using Visual Studio Code, try switching your interpreter. pathfix

14

It also worked here for me. Thank you!

15

Have you try manually activating your env:
source .venv/bin/activate

and then
pip install streamlit

I am using miniconda3 and I am on the base environment. These are the steps that worked for me after installing streamlit using pip (I am using a Mac):

cd ~
ls -la
vim .bash_profile

At this point you are in the vim mode to edit the file you need to click the letter i to go into “insert mode”

Then, add export PATH=“$HOME/.local/bin:$PATH” to the bash profile, in my case I added it in the inner else statement of the conda initialize block, it should look like something like this:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup= blablabla
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if  blablabla
    else
        export PATH="$HOME/.local/bin:$PATH"
        #export PATH="/Users/oda/miniconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

Once you copy the path you need to hit ESC and :wq! to write and quit the bash_profile (save and safely exit the file)
then you can do:

streamlit hello

and you should get a “Welcome to Streamlit” message.

I hope this helps.

Try running streamlit as a python module
E.g
python3 -m streamlit run <filename.py>
