Question

我正在尝试通过Anaconda Navigator安装pydot_ng和graphviz，但我一直收到pydot_ng（1.0.0.15）的错误：

UnsatisfiableError: The following specifications were found to be in conflict:
  - pydot-ng -> python 2.7*
  - python 3.6*
Use "conda info <package>" to see the dependencies for each package.

我该怎么办？没有pydot，我无法使用Keras可视化工具。我已经安装了pydot plus但是Keras似乎在iPython笔记本中拒绝了这个错误。

  File "C:\ProgramData\Anaconda3\lib\site-packages\keras\utils\vis_utils.py", line 131, in plot_model
    dot = model_to_dot(model, show_shapes, show_layer_names, rankdir)

  File "C:\ProgramData\Anaconda3\lib\site-packages\keras\utils\vis_utils.py", line 52, in model_to_dot
    _check_pydot()

  File "C:\ProgramData\Anaconda3\lib\site-packages\keras\utils\vis_utils.py", line 27, in _check_pydot
    raise ImportError('Failed to import pydot. You must install pydot'

ImportError: Failed to import pydot. You must install pydot and graphviz for `pydotprint` to work.

Answer 1

为Python 3.5 +环境安装pydotplus（而不是pydot）。

sudo conda install pydotplus

sudo conda install graphviz

确保在代码中导入'pydotplus'（而不是pydot）。

Answer 2

您正在尝试在Python 3.5环境中安装Python 2.7软件包。

也许这会有所帮助： How can I use conda to install pydot?

如何为Windows 64，Python 3.6安装pydot_ng和graphviz？
