我正在尝试从命令行运行模拟 python 软件的巨大进化。该软件依赖于以下 python 包:
1-网络X
2-pyparsing
3-numpy
4-pydot
5-matplotlib
6-graphviz
我得到的错误是这样的:
Couldn't import dot_parser, loading of dot files will not be possible.
initializing with file= initAdapt.py in model dir= ./Test_adaptation//
Traceback (most recent call last):
File "run_evolution.py", line 230, in <module>
gr.write_dot( os.path.join(test_output_dir, 'test_net.dot') )

File "/Library/Python/2.7/site-packages/pydot.py", line 1696, in write
dot_fd.write(self.create(prog, format))
File "/Library/Python/2.7/site-packages/pydot.py", line 1740, in create
self.write(tmp_name)
File "/Library/Python/2.7/site-packages/pydot.py", line 1694, in write
dot_fd.write(self.to_string())
File "/Library/Python/2.7/site-packages/pydot.py", line 1452, in to_string
graph.append( node.to_string()+'\n' )
File "/Library/Python/2.7/site-packages/pydot.py", line 722, in to_string
node_attr.append( attr + '=' + quote_if_necessary(value) )
TypeError: cannot concatenate 'str' and 'int' objects
我已经尝试过针对堆栈溢出的类似问题建议的解决方案。我仍然得到同样的错误。这是我正在使用的包版本和我的 python 版本。
- 我正在使用 python 2.7.6
- 键入命令
which -a python
会产生结果:“/usr/bin/python”。
1-pyparsing (1.5.7)
2-pydot (1.0.2)
3-matplotlib (1.3.1)
4-graphviz (0.4.2)
5-networkx (0.37)
6-numpy (1.8.0rc1)
有任何想法吗?看到类似问题的解决方案对我不起作用,我认为这个问题在我的情况下可能更为根本。我安装 python 的方式可能有问题。
