Fix NotImplementedError
in NumPy
✅ Solution
The "NotImplementedError" in NumPy often arises when encountering data types or scalar types that lack a specific implementation for a requested operation, especially within functions expecting particular input structures. The fix involves explicitly handling the unsupported data type or scalar type by adding a case to the function's logic that converts it to a compatible type, or by providing a suitable alternative implementation for that type. A common pattern is to cast using `np.asarray` or leverage casting functions to more common, compatible types before performing the operation.
