The first thing to do is wrap our fetch_single function with a delayed decorator. Once outside the loop, we also have to call the compute function from Dask on every item in the fetch_dask array, since calling delayed doesn’t do the computation. Here’s the …

WebTo create a dask array from a numpy array, one can call the from_array () function: darr = da.from_array(my_numpy_array, chunks=4096) The chunks keyword tells dask the size of a chunk of data. If the numpy array is 3-dimensional, the chunk size provide above means that one chunk will be 4096x4096x4096 elements.
