3.1 Array 除了linalg库,numpy系列基本都有实现。 import dask.array as da x = da.random.uniform(low=0, high=10, size=(10000, 10000), # normal numpy code chunks=(1000, 1000)) # break into chunks of size 1000x1000 y = x + x.T - x.mean(axis=0) # Use normal syntax for high leve...
Process the message in successive 512-bit chunks: break message into 512-bit chunks for each chunk create a 64-entry message schedule array w[0..63] of 32-bit words (The initial values in w[0..63] don't matter, so many implementations zero them here) copy chunk into first 16 words ...
Dask的使用是非常清晰的,如果你使用NumPy数组,就从Dask数组开始,如果你使用Pandas DataFrame,就从Dask DataFrame开始,依此类推。 importdask.arrayasdax=da.random.uniform(low=0,high=10,size=(10000,10000),# normal numpy codechunks=(1000,1000))# break into chunks of size 1000x1000y=x+x.T-x.mean(a...

Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one—and preferably only one—obvious way to do it. ...

ArrayList that can only hold numbers of a predefined type. Available types and their minimum sizes in bytes are listed above. Type sizes and byte order are always determined by the system, however bytes of each element can be reversed with byteswap() method.from array import array ...
