Question

我设法让TensorFlow（GPU）在Python 3.5.2中运行，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\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:

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启动张量板，还是应该尝试修复CMD中的张量板？提前谢谢。

编辑：

我运行了以下脚本，确定TensorFlow已正确安装：

Answer 1

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

运行Python命令 - 指向tensorboard的main.py文件！ C：\ Software \ Python \ WinPython-64bit-3.5.2＆gt; python C：\ Software \ Python \ WinPython-64bit-3.5.2 \ Lib \ site-packages \ tensorboard \ main.py --logdir = C ：\ SOFTWARE \的Python \代码\ TensorFlow \日志
在WebBrowser上复制socket / url - http://username_or_some_path:6006

Answer 2

如果您使用的是TensorFlow GPU v1.3，请确保使用的是cuDNN v5.1，而不是6.0。

如install guide中所述：

cuDNN v5.1。有关详细信息，请参阅NVIDIA的文档。请注意，cuDNN通常安装在与其他CUDA DLL不同的位置。确保将安装cuDNN DLL的目录添加到％PATH％环境变量中。

如果您使用上述某个软件包的其他版本，请更改为指定的版本。特别是，cuDNN版本必须完全匹配：如果无法找到cuDNN64_5.dll，则不会加载TensorFlow。要使用不同版本的cuDNN，您必须从源代码构建。

Answer 3

您可以创建新的环境变量名称“ tensrobaord” 和vlaue“ python C：\ Anaconda \ Lib \ site-packages \ tensorboard \ main.py”

然后运行命令tensroboard --logdir = your_log_dir

Answer 4

对于tensorflow 2.0.0b1（使用PyCharm时），在tensorboard.exe中有一个名为PyCharmProjectFolder\venv\Scripts的可执行文件，因此您可以从命令提示符直接运行它：

C:\Users\Alex>PyCharmProjectFolder\venv\Scripts\tensorboard.exe --logdir /tmp/data

无法从CMD发布TensorBoard
