[BUG] ImportError: cannot import name '_check_X' from 'imblearn.utils._validation' (/usr/local/lib/python3.10/dist-packages/imblearn/utils/_validation.py) about imbalanced-learn

This is odd because imblearn is already installed on Google Colab as it is a related project to sklearn. When I run this code below it runs without error. Further, Google Colab has the newest version of imblearn installed (check this with import imblearn and then imblearn.version you should see version 0.10.1. Instead of uninstalling and reinstalling packages, consider creating a new notebook on Google Colab cloud notebook and see if the error persists. A similar error was found relating to the relation between sci-kit learn version causing issues with imblearn (see this issue), but it is unlikely that is the case here.

# code I ran from a new notebook on Google Colab that ran witrhout ImportError
import numpy as np
import pandas as pd
from imblearn.over_sampling import ADASYN

X_train = pd.DataFrame(np.random.rand(100, 3), columns=['f1', 'f2', 'f3'])
y_train = pd.Series(np.random.randint(2, size=100))

adasyn = ADASYN(random_state=42)
X_train_resampled, y_train_resampled = adasyn.fit_resample(X_train, y_train)

X_train_resampled_df = pd.DataFrame(X_train_resampled, columns=X_train.columns)
y_train_resampled_df = pd.Series(y_train_resampled)

I also cannot reproduce even after updating imbalanced-learn using pip.
