Kernel Restarting kats_101 at m.fit() #221

Closed viktor-begun closed 2 years ago

viktor-begun commented 2 years ago

Hi, I try to go through kats_101 and at

2.1 An example with Prophet model ...

fit model simply by calling m.fit()

m.fit() ...

I have this message:

"Kernel Restarting The kernel for Kats/tutorials/kats_101_basics.ipynb appears to have died. It will restart automatically."

Then the kernel dies.

The error is:

" INFO:fbprophet:Disabling weekly seasonality. Run prophet with weekly_seasonality=True to override this. INFO:fbprophet:Disabling daily seasonality. Run prophet with daily_seasonality=True to override this. Error in sys.excepthook: Traceback (most recent call last): File "C:\Users\begun\Anaconda3\lib\site-packages\IPython\core\interactiveshell.py", line 1979, in showtraceback stb = value._rendertraceback() AttributeError: 'KeyError' object has no attribute '_rendertraceback'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "C:\Users\begun\Anaconda3\lib\site-packages\IPython\core\interactiveshell.py", line 1981, in showtraceback stb = self.InteractiveTB.structured_traceback(etype, File "C:\Users\begun\Anaconda3\lib\site-packages\IPython\core\ultratb.py", line 1105, in structured_traceback return FormattedTB.structured_traceback( File "C:\Users\begun\Anaconda3\lib\site-packages\IPython\core\ultratb.py", line 999, in structured_traceback return VerboseTB.structured_traceback( File "C:\Users\begun\Anaconda3\lib\site-packages\IPython\core\ultratb.py", line 851, in structured_traceback assert etb is not None AssertionError

Original exception was: KeyError: 'metric_file' "

How to solve it?

I solved it. The problem was that "prophet" was not properly installed. I tried to install it from jupyter notebook, but the installation did not work properly. Since I work on Windows in Anaconda, the solution was to run Anaconda Prompt and install prophet with this command "conda install -c conda-forge prophet". Now kats_101 works.
