Tensorflow v1.10: store images as byte strings or per channel?

心已入冬 提交于 2019-12-18 07:08:18
问题 Context It is known that, at the moment, TF's Record documentation leaves something to be desired. My question is in regards to what is optimal for storing: a sequence, its per-element class probabilities, and some (context?) information (e.g. name of the sequence) as a TF Record. Namely, this questions considers storing the sequence and class probabilities as channels vs as a byte string and whether or not the meta information should go in as features of a tf.train.Example or as the context

stdout redirect from Jupyter notebook is landing in the terminal

天涯浪子 提交于 2019-12-18 06:54:45
问题 So I was trying to redirect stdout for a some of the cells in my Jupyter Notebook to a file with this and then cancel it with this for the rest of the cells. The output from the first set of cells landed in the file like it was meant to. The second set of cells after the cancel command sys.stdout = sys.__stdout__ was giving no output, appearing to do nothing, but I later realised it was landing in the terminal where the notebook was launched. It works perfectly in the Python interpreter with

Why does python behave this way with variables?

问题 I have been trying to understand why python behaves this way, in the block of code below. I have done my research but couldn't find a good answer so I came here to see if anyone can point me in the right direction or provide a good clarification. I understand that it has to do with some old ALGOL principle, but I don't fully understand it. var = 5 def func1(): print(var) func1() def func2(): var = 8 print(var) func2() def func3(): print(var) var = 8 func3() The output of this code is as

南笙酒味 提交于 2019-12-17 20:29:32
问题 I am currently working on a project that requires some communication over the network of a different data types from some entities of a distributed system and I am using ZMQ. The main goal of the project is to have a central node which services clients which can connect at any time. For each client connected, the central node should manage the message communication between the two. Currently, and by the moment, all communication is happening over TCP. The clients need to send and receive

Provide __classcell__ example for Python 3.6 metaclass

两盒软妹~` 提交于 2019-12-17 19:59:32
问题 Per the 3.6.0 docs: CPython implementation detail : In CPython 3.6 and later, the __class__ cell is passed to the metaclass as a __classcell__ entry in the class namespace. If present, this must be propagated up to the type.__new__ call in order for the class to be initialized correctly. Failing to do so will result in a DeprecationWarning in Python 3.6, and a RuntimeWarning in the future. Can someone provide an example of doing this correctly? An example where it's actually needed? 回答1: The

Installing PySide for Python-3.6

若如初见. 提交于 2019-12-17 19:37:54
问题 When I try to install PySide for Python-3.6, it says it is only compatible until Python-3.4. Is there any work-around to get it installed for Python-3.6? Only these Python versions seem to be supported: [(2, 6), (2, 7), (3, 2), (3, 3), (3, 4)]. 回答1: Firstly, it should be pointed out that PySide depends on Qt4, which is no longer officially supported (as of December 2015). In consequence, all development efforts are now focused on PySide2 and Qt5. According to this tracker issue, there are no

Python asyncio.semaphore in async-await function

那年仲夏 提交于 2019-12-17 16:58:14
问题 I am trying to teach myself Python's async functionality. To do so I have built an async web scraper. I would like to limit the total number of connections I have open at once to be a good citizen on servers. I know that semaphore's are a good solution, and the asyncio library has a semaphore class built in. My issue is that Python complains when using yield from in an async function as you are combining yield and await syntax. Below is the exact syntax I am using... import asyncio import
