安装一致版本的angr之后，py3.6.0，grapy.py已复制到相同目录下，运行deflat.py时报错： Traceback (most recent call last): File "deflat.py", line 96, in supergraph = am_graph.to_supergraph(target_function.transition_graph) AttributeError: 'NoneType' object has no attribute 'transition_graph'

@CSU-Dreamstalker According to the error message, it seems to fail to get the target function. Please make sure if you passed the right function address as the command line arg. By the way, did you run the deflat.py with the provided example or your own binary?

Using the provided example. command:python3 deflat.py check_passwd 0x400530
