使用Magpie + Tensorflow / Python3，“ TypeError：join（）参数必须为str或字节，而不是'NoneType'”

Question

我使用的喜鹊 -上Tensorflow一个多标记分类与Word2vec。 使用Python 2.7可以很好地进行培训，但是使用Python 3.x可以在下面给出此错误。 我在Ubuntu 16.04.5 LTS上，奇怪的是Python 3.x代码在另一台Ubuntu计算机上可以正常工作。 我已经更新了我的依赖项：word2vec，喜p，tf，并且不确定出什么问题。

Answer 1

异常来自boto/plugin.py 。 由于某种原因，它获取None而不是某个目录名称的字符串，然后尝试对None下的所有文件进行None ，这失败了，因为您无法os.path.join遍历模式到None 。

那么，为什么要这样做呢？

最有可能的是，您的boto插件目录中存在一些垃圾。 或者，如果不存在，则在您的配置中。 （如果boto在这种情况下具有更好的错误处理能力，那将很好，但是它可能不会经常出现……）

只需卸载并重新安装boto插件即可解决此问题。

对于以后阅读此书的任何人：

如果您的例外情况以此结尾（可能不同的行号和版本号除外）：

  File "/usr/lib/python3/dist-packages/boto/__init__.py", line 1216, in <module>
    boto.plugin.load_plugins(config)
  File "/usr/lib/python3/dist-packages/boto/plugin.py", line 92, in load_plugins
    for file in glob.glob(os.path.join(directory, '*.py')):
  File "/usr/lib/python3.5/posixpath.py", line 89, in join
    genericpath._check_arg_types('join', a, *p)
  File "/usr/lib/python3.5/genericpath.py", line 143, in _check_arg_types
    (funcname, s.__class__.__name__)) from None
TypeError: join() argument must be str or bytes, not 'NoneType'

…这是相同的错误。 但是，如果重新安装boto插件无济于事，则需要创建一个新问题。 （并包括在插件目录中调用find或tree的结果，配置文件的内容以及所有相关的版本号。）
