`Tensor` can be computed by passing it to `tf.Session.run`. `t.eval()` is a shortcut for calling `tf.compat.v1.get_default_session().run(t)`. In the following example, `c`, `d`, and `e` are symbolic `Tensor` objects, whereas `result` is a numpy array that stores a concr...
Quaternions may not be cast to real or complex types.Several array-conversion functions are also included. For example, to convert an Nx4 array of floats to an N-dimensional array of quaternions, use as_quat_array:>>> import numpy as np >>> import quaternion >>> a = np.random.rand(...

A file "How to load and store NumPy array data," which is mostly pointers to a set of narrower how-tos. It says something like: For the simplest solution, see "How to load and store files in X format" For large (>100 GB) datasets, see "How to load and store files in Y format...
To understand np.add.at() in Python, it is a specialized NumPy function for unbuffered, in-place addition at specific array indices, including handling repeated indices. Like, np.add.at(arr, [index1, index2], [value1, value2]) adds values at the specified indices of arr. Meanwhile, np...
