AttributeError "Flags object has no attribute 'c_contiguous'" when using KNeighborsClassifier predict

### Describe the bug

I tried to build a K-nearest neighbor model. I used the default ``weights`` parameter and called the ``predict`` method with a pandas DataFrame object and got the following error:

AttributeError: 'Flags' object has no attribute 'c_contiguous'

### Steps/Code to Reproduce

```python
import pandas as pd
import numpy as np
from sklearn.neighbors import KNeighborsClassifier

X = pd.DataFrame(np.array([[1, 2], [3, 4], [5, 6], [7, 8]]), columns=['a', 'b'])
y = np.array([1, 2, 3, 4])

knn1 = KNeighborsClassifier(n_neighbors=2)

knn1.fit(X, y)

knn1.predict(X)
```

### Expected Results

I expect to get a prediction from the knn1 model. Unfortunately, I get this error

### Actual Results
```
