Numpy commonly used functions
This blog post summarizes some of the major programming numpy functions encountered in the process
1 np.linspace ()
And the like between the output (-1, 1) the number of pitch 15
np.linspace (-1, 1, 15)
2 np.vstack ()
For loop on one line, each line of the stack 15 as the number of 64, to generate a matrix of 64 * 15
np.vstack([np.linspace(-1, 1, 15) for _ in range(64)])
3 np.random.uniform()
64 data randomly sampled from a uniform distribution [1,2], and the size conversion by the (64) to (64, 1)
np.random.uniform(1, 2, size=64)[:, np.newaxis]
