“TypeError:join（）参数必须是str或bytes，而不是'NoneType'”，使用mappie+Tensorflow/Python3

Question

我使用的是magpie-Tensorflow上的多标签分类器Word2vec。使用Python2.7进行培训效果良好，但是对于Python3.x，它给出了以下错误。我使用的是Ubuntu16.04.5LTS，奇怪的是，Python3.x代码可以在不同的Ubuntu机器上运行。我已经更新了我的依赖项：word2vec、mappie、tf，不确定可能出了什么问题。在

Answer 1

异常来自boto/plugin.py。由于某些原因，它获取None而不是某个目录名的字符串，然后尝试全局化None下的所有文件，但失败的原因是无法os.path.join一个glob模式到None。在

那么，它为什么这么做？在

很可能，你的boto插件目录中有一些垃圾。或者，如果不在那里，在你的配置。（如果boto对这种情况有更好的错误处理会很好，但它可能不会经常出现…）

很有可能只要卸载并重新安装boto插件就可以修复它。在

对于以后读到这篇文章的人：

如果异常以以下方式结束（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'

…是同一个虫子。但是，如果重新安装你的boto插件没有帮助，你需要创建一个新的问题。（并包括在插件目录中调用find或tree的结果，以及配置文件的内容，以及所有相关的版本号。）
