我正在使用iptcinfo Python模块从图片中获取元数据,但它向我抛出了很多(无用的)此类警告:
('警告:字符集识别问题',''\ x1b'“)
这是什么意思,如何删除这些警告(或阻止它们发生),因为它们对我的代码似乎不重要?
我的代码很简单:
import iptcinfo
iptc = iptcinfo.IPTCInfo("DSC05647.jpg")

This line in the code似乎正在生成警告:
LOG.warn('problems with charset recognition %s', repr(temp))
您正在看到此消息,因为Python的日志记录模块的默认日志记录级别是"警告"。
在您的代码中,您可以将库的记录器logging level修改为更高,这样您就不会看到警告:
import logging
iptcinfo_logger = logging.getLogger('iptcinfo')
iptcinfo_logger.setLevel(logging.ERROR)
修改:要进行问题排查,请参阅以下内容,了解每个记录器的级别:
for logger_name in logging.Logger.manager.loggerDict:
logger_level = logging.getLogger(logger_name).level
print logger_name, logging.getLevelName(logger_level)

问题在于您使用的模块会执行您不希望模块执行的操作。
print (
'WARNING: problems with charset recognition',
repr(temp))
那些不能像那样残疾的东西。但是,他们是如何实现同样的好SO线程。
Suppress calls to print (python)
所以结合他们两个
import iptcinfo
origianl_IPTCInfo = iptcinfo.IPTCInfo
def patch_IPTCInfo(*args, **kwargs):
import os, sys
class HiddenPrints:
def __enter__(self):
self._original_stdout = sys.stdout
sys.stdout = open('/dev/null', 'w')
def __exit__(self, exc_type, exc_val, exc_tb):
sys.stdout = self._original_stdout
with HiddenPrints():
return origianl_IPTCInfo(*args, **kwargs)
iptcinfo.IPTCInfo = patch_IPTCInfo
iptc = iptcinfo.IPTCInfo("/Users/tarunlalwani/Downloads/image.jpg")
print(iptc)
并且效果很好

首先,我认为iptcinfo应该与Python 2完美配合。
另一个解决方案是修改原始源代码:
负责警告的原始代码
('WARNING: problems with charset recognition', "'\x1b'")
位于iptcinfo.py文件中的第971行。
LOG.warn('problems with charset recognition %s', repr(temp))
您可以分叉原始的github仓库并简单地将其注释掉
#LOG.warn('problems with charset recognition %s', repr(temp))
然后
#Uninstall the original installation
pip uninstall iptcinfo
#Do pip install from your own fork. e.g.:
pip install git+git://github.com/Sulli/iptcinfo.git
