Error in installing on ubuntu 20.04 about g2opy

[Polydynamical]

I had a similar problem. I just deleted the g2opy folder, cloned this repo and just copy pasted the build instructions. After an hour of working on it, it magically works

I deleted everything related to g2opy and then restarted my installation

Change make -j8 to make -j3 or -j2 or if it still doesn't complete: -j1. Watch the memory usage during the build with htop.
If you add -B - it will rebuild from scratch (clean).

Given the point of break, I guess that may be out of memory error - at least I had similar issues, when building on a virtual machine with limited memory and with swap turned off (sudo swapoff -a). RAM usage seemed to reach nearly 7 GB in some places even for 3 threads... on Xubuntu 20.04.

-j8 means 8 threads. So try with -j3 or -j2 etc. If you have a few cores and small memory some complicated parts of the compilation run out of resources.

@Polydynamical
Thanks for your reply. I'm confused and I think that I couldn't get what you mean by ' I just deleted the g2opy folder, cloned this repo and just copy pasted the build instructions'
Which repo did you clone?
Can you explain the steps that you did to get it working?
Thanks

@Polydynamical I already tried what you said. But I still have the same problem!
Can you tell me which version of eigen and pybind11 did you use by installation?
Thanks
