stopped with segmentation fault

[jkstyle2]

First, thanks for your amazing work! While it's really helpful, I really need your help. Here are the summary I'm currently seeing.

When it starts evaluating bird's eye detection, a critical segmentation fault occurs, and it's all stopped. It has been happening in other similar projects, but I can't figure out what the real issues are. It will be so helpful if you could give me some piece of hints. Thanks in advance.

Apart from this issue, I have one more question. How can we decide the 16th value 'score/confidence' in the label? This time, I just put any random number, but I have no idea of calculating the value. Does it come from 2D Detector which usually outputs confidence probability by softmax classification?

Again, thanks for you work, and looking forward to seeing your reply!

@jkstyle2 I have the same problem as you. Have you solved this?

Maybe you should install the following packages

apt-get install texlive-extra-utils
apt-get install gnuplot
apt-get install ghostscript

#1 I met this error because of negative values

Thank you! Solved my problem. But I wondar why it works...

As I understand, 764 to 772 lines of evaluate_object_3d_offline.cpp aim to create png, eps, and pdf files by using gnuplot, ps2pdf, and pdfcrop system tools. These tools are included in the above toolkit libraries.

1. TeX Live: TeX auxiliary programs Myriad additional TeX-related support programs. Includes programs and macros for DVI file manipulation, literate programming, patgen, and plenty more.
2. Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms.
3. Ghostscript is an interpreter for the PostScript® language and PDF files.
