Question

First time here! I get the following warning when I use the pyplot.imshow function:

"Clipping input data to the valid range for imshow with RGB data ([0..1] for floats or [0..255] for integers)."

I know this is a completely expected behavior, given my data. How do I turn this warning off? I have tried

import warnings
warnings.filterwarnings('ignore')

which should turn off all warnings, but for some reason it doesn't help with this particular warning.

Please let me know if this is a duplicate. Thanks.

尝试一下：

import warnings

# do all your preprocessing here...

with warnings.catch_warnings():
    # ...do only the stuff that causes warnings here...

# do everything immediately after here...

我不确定这是否行得通（我希望将其作为注释，但是您不能在注释中进行代码块处理）

edit：在浏览matplotlib代码之后，我认为上面的命令不起作用的原因是实际上它不是警告，而是日志消息。因此，要使用的正确接口是logging。

新解决方案：

import logging

logger = logging.getLogger()
old_level = logger.level
logger.setLevel(100)

# plotting code here

logger.setLevel(old_level)

Disable MatPlotLib warning when using pyplot.imshow
