python - 无法从 CMD 启动 TensorBoard

Question

我已经设法让 TensorFlow (GPU) 在 Python 3.5.2 中工作，但是当我尝试从命令提示符启动 tensorboard 时，我收到此错误:

C:\Users\Alex>tensorboard --logdir /tmp/data
Traceback (most recent call last):
  File "c:\python35\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 18, in swig_import_helper
    fp, pathname, description = imp.find_module('_pywrap_tensorflow', [dirname(__file__)])
  File "c:\python35\lib\imp.py", line 296, in find_module
    raise ImportError(_ERR_MSG.format(name), name=name)
ImportError: No module named '_pywrap_tensorflow'

During handling of the above exception, another exception occurred:

    from tensorflow.python import pywrap_tensorflow

  File "c:\python35\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 20, in swig_import_helper
    import _pywrap_tensorflow
ImportError: No module named '_pywrap_tensorflow'

During handling of the above exception, another exception occurred:

Error importing tensorflow.  Unless you are using bazel,
you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.

有没有办法直接从 Python 启动 tensorboard，或者我应该尝试在 CMD 中修复 tensorboard？提前致谢。

当我运行它时，它会输出:

运行 Tensorboard - 从命令窗口(不是 python - 但 Python 3.5.2 的命令窗口)

1. 运行Python命令 -- 指向tensorboard的main.py文件! C:\Software\Python\WinPython-64bit-3.5.2>python C:\Software\Python\WinPython-64bit-3.5.2\Lib\site-packages\tensorboard\main.py --logdir=C :\Software\Python\Code\TensorFlow\logs

2. 在 WebBrowser 上复制套接字/url -- http://username_or_some_path:6006
