Gym-donkeycar munmap_chunk(): invalid pointer

natasak commented 4 years ago

I am trying to setup the donkeycar with gym-donkeycar (20.9.14) as per instructions (guide/simulator). I have done all the pip install commands but when I try to run the gym-donkeycar I get core dumped (backtrace below). It seems like my graphics driver is causing problems, so any ideas how to solve it?

$ ./donkey_sim.x86_64 
munmap_chunk(): invalid pointer
Aborted (core dumped)

Here is the GDB backtrace I got:

I am using amdgpu graphics drivers (see below).

@Maximellerbach

Is there anything we need to follow up? If not, let's close this.

Maximellerbach commented 3 years ago

I don't know what could be the reason for this error, maybe some Unity stuff I'm not aware of, or simply some drivers Issue. Either case it's not related to DonkeyCar, you can close it.

@natasak is the problem fixed ? Would you want me to get a closer look at it ? If so, repost this issue on this repo. Also please provide the version of the sim you downloaded and maybe also some info on your operating system and stuff that might be related. Thanks.

natasak commented 3 years ago

The problem is fixed with a newer version of the amd drivers. Although they again broke it with incompatibility with higher versions of kernel. I am now on regular open source drivers and simulation is working. Operating system was Ubuntu 20.04 on x86_64.

We can close it, although I was still able to reproduce it in case anyone would want to debug it..

Ok, Thanks a lot for clarfying this issue ! (And sorry for the very late response)
