'numpy.ndarray' object has no attribute 'to'

This error is encountered when trying to convert a NumPy array to a different data type using the `to` method, which doesn't exist for NumPy arrays.
For example, if you have a NumPy array `arr` and want to convert it to a Pandas DataFrame, you may try to use the `to` method like this:
```
import pandas as pd
df = arr.to(pd.DataFrame)
```
However, this will raise the `AttributeError: 'numpy.ndarray' object has no attribute 'to'` error.
To convert a NumPy array to a different data type, you need to use a function or method specific to that data type. For example, to convert a NumPy array to a Pandas DataFrame, you can use the `pd.DataFrame()` function:
```
import pandas as pd
df = pd.DataFrame(arr)
```
This will create a DataFrame with the same data as the NumPy array.
