Write a NumPy program to split a (3,4) array into column-wise chunks using np.hsplit and validate each chunk. Create a function that divides a 2D array into smaller sub-arrays (chunks) and verifies the dimensions of each. Test chunking of a 2D array by splitting rows into multiple segme...

Now that you have done this, it’s time to see what you need to do in order to run the above code chunks on your own. To make a numpy array, you can just use the np.array() function. All you need to do is pass a list to it, and optionally, you can also specify the data...
The array operands are split into small chunks that easily fit in the cache of the CPU and passed to the virtual machine. The virtual machine then applies the operations on each chunk. It's worth noting that all temporaries and constants in the expression are also chunked. The result is ...
因此，如果调用pool.map(my_func, X_test)，这将导致my_func被调用n_imag次，每次调用都有一个大小...
