Streamlit with fbprophet

Using Streamlit
1

Hi,

I failed to install fbprophet with streamlit, or vice-versa.

error during installation

TLDR steps that I took

  1. create and activate new env using Anaconda
  2. use conda to install pip
  3. pip install streamlit
  4. conda install fbprophet.
    • fbprophet → python[version=‘2.7.|3.5.|3.6.*|>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0’]

  • Your python: python=3.8

  • If python is on the left-most side of the chain, that’s the version you’ve asked for.

  1. When python appears to the right, that indicates that the thing on the left is somehow

  2. not available for the python version you are constrained to. Note that conda will not

  3. change your python version to a different minor version unless you explicitly specify

  4. that.

is this the problem? the python version 3.8.1 is too new for both libraries?

Thanks.

documenting it and managed to solved it doing the following.
Not sure the source of the problem is 3.7 as previously I was using 3.8.1(latest)

TLDR

conda create --name streamprophet37 python=3.7 pip #use python 3.7
conda activate streamprophet #activate the environment
conda install libpython m2w64-toolchain -c msys2 # install compiler
conda install numpy cython matplotlib scipy pandas -c conda-forge #ensure dependencies
pip install pystan
pip install fbprophet

Thanks Andrew!

I did follow the installation steps you suggested:

conda create --name streamprophet37 python=3.7 pip #use python 3.7
conda activate streamprophet #activate the environment
conda install libpython m2w64-toolchain -c msys2 # install compiler
conda install numpy cython matplotlib scipy pandas -c conda-forge #ensure dependencies
pip install pystan
pip install fbprophet

… Unfortunately I’m still facing the same errors, which I pasted in the pastebin below:

I’m about to switch to Linux, which should (hopefully!) get rid of this issue! :slight_smile:

Thanks,

Hey @Charly_Wargnier,

On Windows I suggest to install most of your packages through conda to avoid building error nightmares.

And fortunately, fbprohet provides a conda package you can install like so:

conda install -c conda-forge fbprophet

Optionally (because it worked with pip), you could also install pystan using conda, but first do a pip uninstall pystan if you want to do the switch.

conda install -c conda-forge pystan

Btw, even in Prophet documentation, they tell you that The easiest way to install Prophet in Windows is in Anaconda

Thanks Synode! No error when installed that way via miniconda, which is great!

Now when I launch Streamlit (installed via pip install streamlit) I still got a ModuleNotFoundError: No module named 'fbprophet':

It’s worth noting that the environment within which I’m installing Streamlit is virtualenv (I’m enabling it this way ->
virtualenv venv & call venv\Scripts\activate.bat)

I believe this may be the culprit and I’d need a dedicated conda environment to make it work?

I’m off to bed now, I’ll try tmrw :slight_smile:

Thanks,
Charly

This is right, as you’ve installed all your dependencies inside your conda env streamprophet, you’ll have to install it there as well. A simple conda activate streamprophet will do before doing your pip install streamlit
