实质上是一个for loop。 我们可以使用它的一种方式,包装我们之前的函数,在我们传递列时不起作用的函数,并向量化它。它比.apply()快得多,但也比.where()慢了17倍。所以在这种情况下,将坚持使用np.where()! 一些人认为这更快:使用index设置,但事实证明它实际上不是向量化! 代码如下: 4 Multiple conditions 类...
For Multi-GPU cuDF solutions we use Dask and the dask-cudf package, which is able to scale cuDF across multiple GPUs on a single machine, or multiple GPUs across many machines in a cluster.Dask DataFrame was originally designed to scale Pandas, orchestrating many Pandas DataFrames spread across...
As you can see, the components that you saw in the above section return in this small example of a for loop in Python: the for keyword, the variable number, the in keyword, the range() function and the code that you want to execute multiple times, print("Thank you"). That isn't ...
所以,在构建神经网络模型时,我们应该尽量使用矩阵相乘运算,减少 for 循环的使用。 顺便提一下,为了加快深度学习神经网络运算速度,可以使用比 CPU 运算能力更强大的 GPU。事实上,GPU 和 CPU 都有并行指令(Parallelization Instructions),称为 Single Instruction Multiple Data(SIMD)。SIMD 是单指令多数据流,能够复制多...

Problem You need to loop through every item of multiple lists. Solution There are basically three approaches. Say you have: a = ['a1', 'a2', 'a3'] b = ['b1', 'b2'] Using the built-in function map, with a first argument of None, you can iterate on both lists in parallel: ...
pySLAM is a visual SLAM pipeline in Python for monocular, stereo and RGBD cameras. It supports many modern local and global features, different loop-closing methods, a volumetric reconstruction pipeline, and depth prediction models. - luigifreda/pyslam

It creates shellcode for multiple syscalls on multiple platforms that can be quickly utilized within Python scripts. Hands-down, CORE SDI’s implementation of shell creation is the market-leading technology. Example 1.30 is pulled from InlineEgg’s documentation, which was created by CORE SDI ...
