Reading in pickle file throws an error

[lusiki]

When I try to import pickle file in markdown:

{python}
import os
import pandas as pd
from pathlib import Path

input_data_path = 'D:/path'

IMPORT PREPARED DATA

X_train = pd.read_pickle(os.path.join(Path(input_data_path), 'X_train.pkl'))
X_test = pd.read_pickle(os.path.join(Path(input_data_path), 'X_test.pkl'))
y_train = pd.read_pickle(os.path.join(Path(input_data_path), 'y_train.pkl'))
y_test = pd.read_pickle(os.path.join(Path(input_data_path), 'y_test.pkl'))
labeling_info = pd.read_pickle(os.path.join(Path(input_data_path), 'labeling_info.pkl'))

{r}
X_train <- py$X_train

it returns an error:
Error in py_get_attr_impl(x, name, silent) :
AttributeError: 'DataFrame' object has no attribute '_data'

The same code works in python.
