How to specify Search Space in Auto-Sklearn
Solution 1:
You need to edit the config as specified in the docs.
In your case it would be something like:
cs = mdl.get_configuration_space(X, y)
config = cs.sample_configuration()
config._values['classifier:random_forest:n_estimators'] = 1000
pipeline, run_info, run_value = mdl.fit_pipeline(X=X_train, y=y_train,
config=config,
X_test=X_test, y_test=y_test)
