在Cygwin上安装TensorFlow或pip问题

Question

我试过了：

$ pip install tensorflow
Exception:
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/pip/basecommand.py", line 215, in main
    status = self.run(options, args)
  File "/usr/lib/python2.7/site-packages/pip/commands/install.py", line 272, in run
    with self._build_session(options) as session:
  File "/usr/lib/python2.7/site-packages/pip/basecommand.py", line 72, in _build_session
    insecure_hosts=options.trusted_hosts,
  File "/usr/lib/python2.7/site-packages/pip/download.py", line 336, in __init__
    retries = urllib3.Retry(
AttributeError: 'module' object has no attribute 'Retry'
Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/pip/__init__.py", line 233, in main
    return command.main(cmd_args)
  File "/usr/lib/python2.7/site-packages/pip/basecommand.py", line 251, in main
    timeout=min(5, options.timeout)) as session:
  File "/usr/lib/python2.7/site-packages/pip/basecommand.py", line 72, in _build_session
    insecure_hosts=options.trusted_hosts,
  File "/usr/lib/python2.7/site-packages/pip/download.py", line 336, in __init__
    retries = urllib3.Retry(
AttributeError: 'module' object has no attribute 'Retry'

那：

$ pip3 install tensorflow
Exception:
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/pip/basecommand.py", line 215, in main
    status = self.run(options, args)
  File "/usr/lib/python3.6/site-packages/pip/commands/install.py", line 272, in run
    with self._build_session(options) as session:
  File "/usr/lib/python3.6/site-packages/pip/basecommand.py", line 72, in _build_session
    insecure_hosts=options.trusted_hosts,
  File "/usr/lib/python3.6/site-packages/pip/download.py", line 336, in __init__
    retries = urllib3.Retry(
AttributeError: module 'pip' has no attribute 'Retry'
Traceback (most recent call last):
  File "/usr/bin/pip3", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python3.6/site-packages/pip/__init__.py", line 233, in main
    return command.main(cmd_args)
  File "/usr/lib/python3.6/site-packages/pip/basecommand.py", line 251, in main
    timeout=min(5, options.timeout)) as session:
  File "/usr/lib/python3.6/site-packages/pip/basecommand.py", line 72, in _build_session
    insecure_hosts=options.trusted_hosts,
  File "/usr/lib/python3.6/site-packages/pip/download.py", line 336, in __init__
    retries = urllib3.Retry(
AttributeError: module 'pip' has no attribute 'Retry'

但无济于事。我重新安装了python [23] -pip *和python [23] -urllib3，但没有任何改变。

我不知道这是否与TensorFlow或某些pip / urllib3相关。有人可以帮忙吗？我想安装TF，但也许还有其他问题需要先修复？看起来像一些依赖性问题...
