Now I would like to get the boundaries array([[True,True,True,True], [True,False,False,True], [True,False,False,True], [True,True,True,True]]) Great if efficient and works for arbitrary number of dimensions, but it has to work at least 3. The array is not a necessarily a hypercu...

TensorFlow的运算基本上都是基于张量的。张量是多维array,跟numpy类型,也可以通过方法和tensor进行转换,比如tensor支持.numpy()方法转换为numpy array,两者在进行运算时,也会自动转换: import numpy as np ndarray = np.ones([3, 3]) print("TensorFlow operations convert numpy arrays to Tensors automatically") ...
