Trouble using fbprophet with Spyder on mac

[kyliem21]

Hi everyone,

I'm fairly new to Python, and I'm struggling to correctly implement fbprophet with the Anaconda Navigator. Pystan and gcc are installed. I've read numerous other threads, and I've tried the following approaches (including multiple iterations of installing and uninstalling pystan, fbprophet, cython):

pip install fbprophet – results in: "Failed building wheel for fbprophet"
conda install -c conda-forge fbprophet – seems to have properly executed

From the Anaconda Navigator, when I open Spyder and attempt to import fbprophet, I get the following error: "cannot import name 'IncludeCode'", which refers back to what I believe is line 32 in the Cython Compiler Module.Node.py script (error messages are included below.)

However, when I import fbprophet in a Jupyter notebook, the import is successful and I have no issues running a script that relies on fbprophet.

Has anyone run into this issue before, or does anyone have suggestions for a fix? Any guidance would be greatly appreciated!

Error:
File "/Users/kylie/anaconda/lib/python3.6/site-packages/Cython/Compiler/ModuleNode.py", line 32, in from .Code import UtilityCode, IncludeCode

ImportError: cannot import name 'IncludeCode'

I also encountered this problem. Have you found a solution?

The wheel failing to build might just be due to #401, which means that if you run pip install a second time it will work.

So just to be sure I have this right, import fbprophet works in Jupyter but not in Anaconda. Anaconda has a separate build environment from system Python, and I'm guessing Jupyter is running on system Python and not via Anaconda, right?

So it seems to me that things are working in system Python (the pip install was successful) but not working in Anaconda due to its C++ compiler not working.

Could you check if PyStan is working in Anaconda by running:

import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)  # this will take a minute
y = model.sampling(n_jobs=1).extract()['y']
y.mean()  # should be close to 0

If that doesn't work (my expectation), then try reinstalling PyStan in Anaconda. Do

conda install gcc

and

conda install -c conda-forge pystan

and see if PyStan works then.
