参考:
pydot and graphviz error: Couldn't import dot_parser, loading of dot files will not be possible
NameError: global name 'dot_parser' is not defined 解决方法
在使用pydot包时发现dot_parser未在程序中定义:
Couldn't import dot_parser, loading of dot files will not be possible.
Traceback (most recent call last):
File "pifo_compiler.py", line 153, in
g= pydot.graph_from_dot_data(x)
File "/usr/local/lib/python2.7/dist-packages/pydot.py", line 220, in graph_from_dot_data
return dot_parser.parse_dot_data(data)
NameError: global name 'dot_parser' is not defined
这是因为当前pydot和pyparsing的版本不兼容,解决方法是使用pip安装pydot和pyparsing的旧版本:
pip install pyparsing==1.5.7
pip install pydot==1.0.28
2018.4
