Unable to install pystan & fbprophet

vaishnavi

I tried installing "pystan" and fbprophet by mentioning them in the "Code envs" section. When I click on "Save and Update" I am getting the below error:

Hi @vaishnavi
,

fbprophet relies on pystan, so please try installing pystan first and switch fbprophet to prophet (newer version).

Please try adding the following to your list of installed packages:

pystan<3
prophet

If you receive errors, you can either attach the logs here. Alternatively, you may send an email to support, or live chat us and attach a code env diagnostic.

Thanks,

Jordan

@JordanB
Thanks, I made the changes you had mentioned above and the installation worked. For further support how to start the live chat ?

I want to use the Prophet model for timeseries forecasting in Dataiku. As we do not have Prophet model in the dataiku's list of models, If I use it in the python code recipe and create a model, how to access that model in other projects ?

Hi @vaishnavi
,

The ML API allows you to manipulate ML Tasks, and use them to train models, inspect their details, and deploy them to the Flow.

Once deployed to the Flow, the Saved model can be shared between projects.

You may share project objects such as models with other projects by going to your saved model.

Selecting the model you want to share from the list, and choose "Share" in the actions menu:

Please see our documentation on Shared Objects for more details: https://doc.dataiku.com/dss/latest/security/shared-objects.html?highlight=shared

You can also save your model to a file using the pickle module and load that file into any of your projects.

If you have any questions, please let us know.

Thanks!

to note: if you are working with containerized execution, dataiku expects centOS7 based containers. centOS 7 doesnt support C++14, so youll need to pin pystan at pystan==2.18.0.0
