我正在尝试将关键字添加到 JPG 文件中的 IPTC 数据中，但失败得很惨。我可以使用 iptcinfo3 库读取关键字，并且似乎将关键字附加到当前关键字列表中，但是在尝试将这些关键字写回 JPG 文件时失败了，如果不是更早的话。错误消息对我来说有点不清楚，实际上可能引用了 new 关键字的附加（尽管 print 语句似乎表明它采取了）。

我已经尝试了三个不同的元数据库（似乎没有一个标准），这是我用它们中最远的一个（甚至无法安装一个并且无法运行第二个） . 这看起来很基本，但我无法弄清楚，也无法调整我在网上看到的其他几个代码示例来工作，包括 iptcinfo3 的示例代码片段。

当前的错误消息是：

| => pipenv run python editMetadata.py
WARNING: problems with charset recognition (b'\x1b')

[b'Gus', b'frog']
Traceback (most recent call last):

代码：

from iptcinfo3 import IPTCInfo
import os


# Create new info object
info = IPTCInfo('Gus.jpg')

# Print list of keywords
print(info['keywords'])

# Append the keyword I want to add
info['keywords'].append(b'frog')

# Print to test keyword has been added
print(info['keywords'])

# Save new info to file
info.save()
info.save_as('Gus2.jpg')

而不是附加使用等于“=”

from iptcinfo3 import IPTCInfo

info = IPTCInfo('Gus.jpg')
print(info['keywords'])

# add keyword
info['keywords'] = ['new keyword']

info.save()
info.save_as('Gus_2.jpg')

我有同样的错误。取决于文件，这似乎是保存的问题。

from iptcinfo3 import IPTCInfo
info = IPTCInfo('image.jpg', force=True)
info.save()

这给了我同样的错误。
