WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebWith np.isnan(X) you get a boolean mask back with True for positions containing NaNs.. With np.where(np.isnan(X)) you get back a tuple with i, j coordinates of NaNs.. Finally, with np.nan_to_num(X) you "replace nan with zero and inf with finite numbers".. Alternatively, you can use: sklearn.impute.SimpleImputer for mean / median imputation of missing values, or WebI printed the entire stack_predict dataframe, and it's shape is consistent with the inputs provided.
