Question

我使用jupyder笔记本：

from IPython import display
graph = net_drawer.GetPydotGraph(train_model.net.Proto().op, 'mnist', rankdir='LR')
#graph.write_png("lenet.png")
display.Image(graph.create_png(), width=800)

我遇到此错误：

---------------------------------------------------------------------------
OSError                                   Traceback (most recent call last)
<ipython-input-11-95f1d8e2feb8> in <module>()
      2 graph = net_drawer.GetPydotGraph(train_model.net.Proto().op, 'mnist', rankdir='LR')
      3 #graph.write_png("lenet.png")
----> 4 display.Image(graph.create_png(), width=800)

   1663             name = 'create_{fmt}'.format(fmt=frmt)
   1664             self.__setattr__(name, new_method)

   1866                     prog=prog)
-> 1867                 raise OSError(*args)
   1868             else:
   1869                 raise

OSError: [Errno 2] "dot" not found in path.

我可以在终端和pycharm中成功运行代码，但是在jupyder Notebook中失败。请你帮助我好吗？谢谢！此外，我已经成功安装了dot，例如：

sudo apt-get insall graphviz
pip install pydot

Answer 1

brew install graphviz 对我有用。
