This fails for the same reason as: import numpy as np arr = np.array ( [1.0, 2.0, 3.0], dtype=object) np.sin (arr) # AttributeError: 'float' object has no attribute 'sin'. When np.sin is called on an object array, it tries to call the sin method of each element. If you know the dtype of θr.values, you can fix this with:

Jun 30, 2019 · No, because np.sin (np.array (1, dtype=object)) has the same problem. The cause here is: 70**11 is not an array, so is coerced to one. 70**11 is too large to fit in an int64 array, so an object array types is chosen. np.sin (object_array) is only supported if the objects within have a sin method. Loading.
