Fix SystemError

✅ Solution

SystemError in NumPy often arises from incorrect type handling during operations like `astype` conversions or `np.dot` when the input array dtypes are fundamentally incompatible. To fix this, carefully examine the input array dtypes and use `astype` or other explicit conversion methods to ensure they are compatible before performing the operation. If the dtypes should work together, the library itself may have an issue so reporting to the numpy team could be useful.
