Type error when implementing fitting models from orbit.models.dlt

[nportman]

I attempted to reproduce the results of ETSFull model on load_iclaims() data using code example provided in orbit documentation, however, I ran into TypeError issue. I did the install of orbit-ml package on Windows 10, and below is the code that I used:

%matplotlib inline import orbit from orbit.utils.dataset import load_iclaims from orbit.models.dlt import ETSFull from orbit.diagnostics.plot import plot_predicted_data df = load_iclaims() date_col = 'week' response_col = 'claims' df = load_iclaims() date_col = 'week' response_col = 'claims' dlt = ETSFull( response_col=response_col, date_col=date_col, seasonality=52, seed=8888, ) dlt.fit(train_df)

Here is the output of the above code:

TypeError Traceback (most recent call last)

hi @nportman, how did get orbit installed on your machine? pip or conda? did you use a virtual env?

Same issue here.

I'm using pyenv (Python 3.7) on Linux. I installed orbit via pip. Seems to works fine if I install Orbit from code.
