[yt-users] Yt line query: Segmentation fault (core dumped)

[Chongchong He]

Dear Sir/Madam,

I came into a problem when using yt to deal with my RAMSES data. The procedures to produce the error and some info is as follow. Do you have any idea what’s going wrong here?

I use the data from yt-project.org/data/ <http://yt-project.org/data/>, in the row of ramses_extra_fields_small. The python code that generates this issue is uploaded to http://paste.yt-project.org/show/7203/ <http://paste.yt-project.org/show/7203/> 

On macOS Sierra 10.12.5

The print-out message:
