Dask 在大多数基于行的组合中使用 stack_partitions 技术,除非所有输入 DataFrame 的分区都已知,它们没有被很好地排序,并且你要求 Dask interleave_partitions。在输出中,stack_partitions 技术只有在输入分区已知且有序时才能提供已知分区。如果所有分区都已知但排序不好,并且你设置了 interleave_partitions,Dask ...
Later, on line 17, you stack and interleave the two channels, creating the stereo signal ready to be written into your WAV file. The conversion of integers to 16-bit PCM samples gets accomplished by calling NumPy’s .astype() method with the string literal "<h" as an argument, which ...
We should not interleave numpy‘s vectorized operation along with a Python loop. This slows down performance drastically, as the code is iterating using native Python. 我们不应该将 numpy的向量化操作与Python循环一起插入。 由于代码正在使用本机Python进行迭代,因此这会极大地降低性能。 For example, the...

and you ask Dask tointerleave_partitions. Thestack_partitionstechnique is able to provide known partitioning in its output only when the input divisions are known and well ordered. If all of the divisions are known but not well ordered and you setinterleave_partitions, Dask will use a ...

This ensures that comprehensions always immediately return a container of the appropriate type (rather than potentially returning a generator iterator object), while generator expressions won’t attempt to interleave their implicit output with the output from any explicit yield expressions. In Python 3.7...
Hyperthreading presents a virtual second CPU to the host operating system (OS), and clever hardware logic tries to interleave two threads of instructions into the execution units on a single CPU. When successful, gains of up to 30% over a single thread can be achieved. Typically this works ...

For example, Microsoft Animation ActiveX control in 6.0 allows remote hackers to run arbitrary code with an audiovisual interleave (AVI) file. This causes memory corruption and an 'allocation error.' (CVE Details, 2013). Enterprise Edition 6.0 is also vulnerable when a long CommandName line or ...
