Pseudorandom Number Generators 2. local and online Multiplayer in same project. I just downloaded and installed. I do not know how to fix this problem. The former approach avoids explicitly creating the vector 20:50 (not a big deal for this example, a big deal if you're trying to select 10 elements from a very large range of values whose length you know.) Notes. And numpy.random.rand(51,4,8,3) mean a 4-Dimensional Array of shape 51x4x8x3. NumPy offers the random module to work with random numbers. Please reopen if needed. You can select one of them at random (with random.choice), or if you plan on using many of them and you don't want to repeat yourself, you can use random.shuffle, then iterate.
