local variable 'forecast_df_folds' referenced before assignment

[Vaderv]

Running into issue when running:

model.fit(
traindata=dataset,
# traindata=file_path, # Alternately, you can specify the file directly
ts_column=ts_column,
target=target,
cv=3,
sep=sep)

I get the error:
local variable 'forecast_df_folds' referenced before assignment

Exception occurred while building Prophet model...
Prophet object can only be fit once. Instantiate a new object.
FB Prophet may not be installed or Model is not running...
Traceback (most recent call last):

same error on Google Colab notebook.

[GGA-PERSO]

auto_ts/init.py
not an expert but I think it should be
forecast_df_folds = None
instead of
forecasts = None

?

I am also getting the same error. Please let me know if you know how to fix that problem. Thanks in advance.

Hi Baisalis, Vaderv, Hurkaine and t1masavin:
I am sorry you are all getting this problem. The reason you get this error is that it is a catch-all error in case anything goes wrong with using your data to build a Facebook prophet model. So unless you can point me to the right Github notebook where you have your code or paste a sample of your data, I won't be able to fix it.

In addition, you can also send an email to rsesha2001 at gmail to get a copy of the notebook or colab file so I can look it over and fix if there are any problems with data or my code.

Also please try upgrading to the latest version. It usually has bug fixes that I find and I am also constantly testing it with new data sets and updating it.

$ pip install auto-ts --upgrade --user

Hope this helps,
Ram

Hi all: I have found the error and fixed it - please upgrade Auto-TS to the latest version by: $ pip install auto-ts --upgrade You should see version 0.0.36 and that should work.

I have just received this error again. Any advice?

Hi @AutoViML

I encountered the same error and traced it to using kwargs = {'iter':1e2} on the following lines:
https://github.com/AutoViML/Auto_TS/blob/master/auto_ts/models/build_prophet.py#L234
https://github.com/AutoViML/Auto_TS/blob/master/auto_ts/models/build_prophet.py#L254
https://github.com/AutoViML/Auto_TS/blob/master/auto_ts/models/build_prophet.py#L566

The reason is that 1e2 evaluates (at least on SageMaker Linux) to 100.0 (float) and Prophet expects an int which raises the error above due to the try / catch above.

Once I changed the line to kwargs = {'iter':100} it works as expected.

I have also encountered this problem. Have you solved this problem

[ravik4985]

Getting error local variable 'forecast_df_folds' referenced before assignment. can somebody suggest a resolution upgrading auto-ts not helping.

[cgobat]

For future visitors to this thread: #98 resolved this issue.

[Fisixus]

Delete this part model_type='best' from "model = auto_timeseries(score_type='rmse')" this line.
This issue belongs to the Prophet model.

still getting error is this fix on a branch still?

[AutoViML]

Can you try upgrading to the latest version 0.71? I have made all the changes mentioned in this thread.
