我想要从命令行运行一个巨大的演化模拟Python软件。该软件依赖以下Python包:
1. networkX
2. pyparsing
3. numpy
4. pydot
5. matplotlib
6. graphviz
我遇到的错误是:
1. networkX
2. pyparsing
3. numpy
4. pydot
5. matplotlib
6. graphviz
我遇到的错误是:
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):

dot_fd.write(self.create(prog, format))

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
我已经尝试了stackoverflow上类似问题的解决方案,但仍然出现相同的错误。这是我使用的软件包版本和Python版本。
- 我使用的是Python 2.7.6
- 输入命令
which -a python
的结果为:“/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)
有什么想法吗?鉴于类似问题的解决方案对我不起作用,我认为问题可能更根本。也许是我安装Python的方式有问题。
