Getting {ValueError} 'a' must be 1-dimensoinal for list of lists from np.random.choice

In case of an array I would do the following:

xor = np.array([[0,0,0],
       [0,1,1],
       [1,0,1],
       [1,1,0]])
rnd_indices = np.random.choice(len(xor), size=200)

xor_data = xor[rnd_indices]

If you want a random list from xor, you should probably be doing this.

xor[np.random.choice(len(xor),1)]

You can use the random package instead:

import random
input_x = [random.choice(xor) for _ in range(200)]
