Description

I am trying to run an fbprophet model on hierarchical time series data. It was working fine till now. All of a sudden it is showing pickle file not found for a particular category

What I Did

kwargs = {'yearly_seasonality':True,'weekly_seasonality':True,'changepoint_prior_scale':0.5}
clf = HTSRegressor(model='prophet', revision_method='WLSS', n_jobs=4,**kwargs,low_memory=True)
model = clf.fit(hierarchy_bottom_level, hierarchy)
RemoteTraceback:
"""
