Segmentation fault (core dumped)

[JJHu1993]

When I run demo exp_inverse.py , the error occurs: Segmentation fault (core dumped)
I found the error comes from arcsim.init_physics(out_path+'/conf.json', out_path+'/out%d'%epoch,False)
What should I do?

Hi, what's your command to run exp_inverse.py? Are you in the pysim directory when running this script?

[JJHu1993]

I run the demo through python exp_inverse.py and I am in the pysim directory.
The error comes from line Tensor min_angle = infinity;in Io.cpp
When I modified it into Tensor min_angle = std::numeric_limits<double>::infinity()*ONE; , the error disappeared. I don't know why, The original code gives infinity the std::numeric_limits<double>::infinity()*ONE. It's the same.

After that, another segmentation fault error occurs. It comes from obstacles.resize(json.size()); in conf.cpp.

Thanks for your feedback about the infinity issue, and I change this to a #define. Can you please try if this solves your problem? As for the next segmentation fault, can you see if it's caused by resize() of jason.size()?

[JJHu1993]

The error of obstacles.resize(json.size()) also comes from infinity , I use your new code and the error disappears. Thanks.
