As far as I know, OpenCV VideoWriter has no support for HEVC encoding (yet). I recommend you using FFmpeg as sub-process, and PIPE the rendered frames to stdin input stream of ffmpeg. You may use Python binding for ffmpeg like ffmpeg-python, or execute ffmpeg using Python subprocess. Using ffmpeg, you have much more control over … Read more
Borrowing heavily from aioconsole, if you would rather avoid using an external library you could define your own async input function: async def ainput(string: str) -> str: await asyncio.get_event_loop().run_in_executor( None, lambda s=string: sys.stdout.write(s+’ ‘)) return await asyncio.get_event_loop().run_in_executor( None, sys.stdin.readline)
A map object is a generator returned from calling the map() built-in function. It is intended to be iterated over (e.g. by passing it to list()) only once, after which it is consumed. Trying to iterate over it a second time will result in an empty sequence. If you want to save the mapped values … Read more
The aspect ratio of an imshow plot is automatically set such that pixels in the image are squared. This setting is stronger than any of the subplots_adjust or gridspec settings for spacing. Or in other words you cannot directly control the spacing between subplots if those subplots have their aspect set to “equal”. First obvious … Read more
Edit: Apparently the carriage return \r and the backspace \b won’t actually work within Idle because it uses a text control that doesn’t render return/backspace properly. You might be able to write some sort of patch for Idle, but it might be more trouble than it’s worth (unless you really like Idle)
Though you’re running a subsidiary event loop (really don’t do that!) it still shares the same registry of event handlers as the outer loop, so events coming in are handled in the inner loop just as in the outer one. (There’s a common piece of low-level event handling code that reaches deep into the OS … Read more
object is the default container capable of holding strings, or any combination of dtypes. If you are using a version of pandas < ‘1.0.0’ this is your only option. If you are using pd.__version__ >= ‘1.0.0’ then you can use the new experimental pd.StringDtype() dtype. Being experimental, the behavior is subject to change in future … Read more
ChromeDriver is the standalone server which implements WebDriver’s wire protocol for Chromium. Chrome and Chromium are still in the process of implementing and moving to the W3C standard. Currently ChromeDriver is available for Chrome on Android and Chrome on Desktop (Mac, Linux, Windows and ChromeOS). As per the current WebDriver W3C Editor’s Draft The following … Read more
In the Latest Tensorflow Version (2.2), when we Save the Model using tf.keras.models.save_model, the Model will be Saved in not just a pb file but it will be Saved in a Folder, which comprises Variables Folder and Assets Folder, in addition to the saved_model.pb file, as shown in the screenshot below: For example, if the … Read more
Python’s default generator is a Mersenne Twister with a state space that is 19937 bits, much larger than what you think of as the seed. You can think of it conceptually as three functions: f(seed) -> state0 g(statei) -> statei+1 h(statei) -> outcomei When you start with a seed value using random.seed(), it generates a … Read more
