The NumPy ndarray: A Multidimensional Array Object One of the key features of NumPy is its N-dimensional array object, or ndarray, which is a fast, flexible container for large data sets in Python. Arrays enable you to perform mathematical operations on whole blocks of data using similar synta...
in create_empty_array * Fix check_observation_space with spaces equality * Raise an exception when operations are out of order in AsyncVectorEnv * Add version requirement for cloudpickle * Use a state instead of binary flags in AsyncVectorEnv * Use numpy.zeros when initializing observations in ...
The reason for this is that XLA has no searchsorted primitive, so it can be somewhat slow in practice. And by doing static concatenation rather than dynamic insertion, all the operations will be JIT compatible. Hope that helps! Hi - it's a good question! Actually I suspect the best way ...

Calculates the square of every element of the object in vectorized fashion. In addition, the ndarray class provides certain methods that allow vectorized operations. They often also have counterparts in the form of so-called universal functions that NumPy provides: In [15]: a.mean() Out[15]:...
