Submission Error with base line

I get an error with the base line architecture for inference.
I get the error:
File “/home/appuser/miniconda/envs/py/lib/python3.8/site-packages/sklearn/preprocessing/”, line 791, in transform
X = self._validate_data(X, reset=False,
File “/home/appuser/miniconda/envs/py/lib/python3.8/site-packages/sklearn/”, line 436, in _validate_data
self._check_n_features(X, reset=reset)
File “/home/appuser/miniconda/envs/py/lib/python3.8/site-packages/sklearn/”, line 372, in check_n_features
raise RuntimeError(
RuntimeError: The reset parameter is False but there is no n_features_in
attribute. Is this estimator fitted?
it seems that it is due to the scaler…I fitted the scaler (and model) in google colab.
Many Thanks in advance.

I had the same error, and somewhere above in the error trace it was written that the version in which you save the scaler is different from the one used in the docker. What helped me to solve the error is upgrading the scikit-learn to the latest one.
Good luck!
