`results=FALSE` and `results='hide'` both not working as expected for python code chunks

With the following RMarkdown:

```{python results=FALSE}
from sklearn.datasets import load_digits
from sklearn.model_selection import train_test_split
X,y = load_digits(return_X_y=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33)
from sklearn.neighbors import KNeighborsClassifier
model = KNeighborsClassifier(n_neighbors=3)
model.fit(X_train, y_train)


Although I have set `results=FALSE` (or results='hide'), the resulting Markdown still includes the results from python, and isn't marked as  ` knitr-output` but `{=html}`:

from sklearn.datasets import load_digits
from sklearn.model_selection import train_test_split
X,y = load_digits(return_X_y=True)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.33)
from sklearn.neighbors import KNeighborsClassifier
model = KNeighborsClassifier(n_neighbors=3)
model.fit(X_train, y_train)
