Prophet: Unable to Install Version 3

[mujeebla]

I have been working with version 2.1 for a while but would like to use some of the new updates included in V3.0, specifically the multiplicative seasonality mode.
I uninstalled fbprophet and tried reinstalling.
Here's the error I got

$ pip install fbprophet

Kindly help.

[bletham]

Is this in Linux or OSX?

I know you already had v0.2 before, but would you check that something hasn't messed up in pystan's ability to compile the model:

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

[mujeebla]

I got a long error. This is the main theme

CompileError: command 'gcc' failed with exit status 1

[bletham]

That indicates that pystan is not working, likely because the C++ compiler is not configured correctly. Is this OSX or Linux? If Linux, check that all of the packages in the "Linux" section from here (https://facebook.github.io/prophet/docs/installation.html) are installed. Also, is this a VM? Stan requires a significant amount of memory to compile the models, and this error can occur if you run out of RAM while it is compiling.

[mujeebla]

It's OSX and I think my system memory is sufficient

[mujeebla]

I tried to install pystan and got this message

pip3 install pystan

that pystan check also fails with same exit status 1.

I'm on solus os if it means anything.

[bletham]

@mujeebla PyStan will successfully install even if the C++ compiler is not functioning correctly. Try

conda install gcc

I think this may be relevant: https://stackoverflow.com/questions/43091071/error-command-gcc-failed-with-exit-status-1-while-installing-pygresql

@vidje can you run this code to check if PyStan is working?

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 not, then the most likely issue would be having <4Gb of RAM. Next to try after checking that would be checking that GCC is up-to-date.

i've 8gb ram and gcc should be latest as solus is a rolling distro

[bletham]

@vidje The issue is then that PyStan is not working correctly. I don't have a whole lot of debugging experience myself for PyStan, or familiarity with solus so I'm not sure how much help I'll be able to be. This issue is consistent with not having the dev package for python (python3-dev in debian-based flavors) or the build tools (build-essential), but it looks like it could also be with cython. If you look at the PyStan github you can probably find other paths for debugging: https://github.com/stan-dev/pystan/issues/206

[DominiquePaul]

@bletham Thanks for the support in this thread. I had the same issue and running
conda install gcc
did the trick.

Lonely：if you don't have conda or even you have conda，you can use these two simple command:
python3 -m pip install pystan==2.17.1.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
and then
python3 -m pip install fbprophet -i https://pypi.tuna.tsinghua.edu.cn/simple
now, you may success~

i have same problem, so i downgrade 2.18 or 2.17, it's solve my problem i refer from this
https://github.com/stan-dev/pystan/issues/583

[youssefHamane]

hello,

I suggest installing anaconda from here https://www.anaconda.com/distribution/#windows
and after that try to install it with command :
conda install -c conda-forge fbprophet
https://anaconda.org/conda-forge/fbprophet
PS : You must use Anaconda Prompt not windows.

Best Regards,
Youssef HAMANE
