It will return a dictionary containing the program names as keys
Location under the "Program Files" directory. It will look for 'dot', 'twopi' and 'neato' in the default install Thirdly: Default install location (Windows only) Specified in the PATH environment variable. It will look for 'dot', 'twopi' and 'neato' in all the directories This requires Mark Hammond's pywin32 is installed. Pydot无法找到graphviz，手动修改pydot.find_graphviz()函数，例如我是这样改的： def find_graphviz (): """Locate Graphviz's executables in the system. (f, outfile= "./pics/symbolic_graph_opt.png", var_with_name_simple= True) error1： Failed to import pydot
(b, outfile= "./pics/symbolic_graph_unopt.png", var_with_name_simple= True) So it seems that importing a dot parser is a problem, but I don't really know what that means or how to go about getting a solution.在按照Theano Tutorial编写查看Theano图结构时遇到了点问题。示例代码： import theanoĪ = ( "a") # declare symbolic variableī = a + a ** 10 # build symbolic expressionį = theano.function(, b) # compile function print f() # prints `array()` If I try to run rosdep install -from-paths src -ignore-src -rosdistro groovy -y, one of first errors I get is Couldn't import dot_parser, loading of dot files will not be possible. The output is: Downloading/unpacking pyparsing=1.5.7 If I input the command sudo pip install pyparsing=1.5.7 Unfortunately, it doesn't look like it's working.

I am trying to install ROS on my MacBook Pro, with OS 10.8.3.
