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) 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()`
