在python中我们使用buffer类型时可以将其转换为str类型。 如果obejct的类型为<type 'buffer'> ,可以使用str(object)将其转换为字符串类型。 在转换为字符串类型后如果无法使用+等字符串,则可能是python的str类型的编码方式与buffer的编码格式不一致导致的。 如果buffer使用的是unicode编码,则需要在模块中使用以下代码,...

Q: First off, great work! Do you have any suggestions for understanding when to use coroutines and when to not use them? They're too new to see what kind of performance they bring to the table, and I don't see much in terms of comparisons with other methods yet. ...
If you are working with very large batch sizes and do not need support for Decimal/strings we provide a petastorm.pytorch.BatchedDataLoader that can buffer using Torch tensors (cpu or cuda) with a signficantly higher throughput. If the size of your dataset can fit into system memory, you...
In earlier versions of Python (up to 1.5a3), scripts or modules that needed to use site-specific modules would place ``import site'' somewhere near the top of their code. Because of the automatic import, this is no longer necessary (but code that does it still ...
因为默认情况下,Python采用的是ascii编码方式,如下所示: python -c "import sys; print sys.getdefaultencoding()" ascii 1. 2. 而Python在进行编码方式之间的转换时,会将 unicode 作为“中间编码”,但 unicode 最大只有 128 那么长,所以这里当尝试将 ascii 编码字符串转换成"中间编码" unicode 时由于超出了其...
It has two axes, and can be indexed using a pair of numbers in the range 0 to 1: >>> a[1,1] 'D' However, there’s no such thing as “two-dimensional” computer memory, at least not in common use. The elements are actually stored in a one-dimensional buffer:...
