Import error in executing the app image

[anirban6908]

Hey @hernando When I try to execute the app Image using ./rtneuron_x86_64.AppImage --app I am getting this error

ImportError: libturbojpeg.so.0: cannot open shared object file: No such file or directory

Thanks

[hernando]

Hmm, I thought we had fixed that error, which is a missing library that should be shipped with the image. Install libturbojpeg in your system with apt or the equivalent library in rpm based systems (I can't remember the package name in this case)

Ok it worked.!( for Centos 7) I get the ipython prompt but still getting a few error messages

I tried to install Monsteer from the repo but getting some configuration error. I guess I can ignore this for now. Wanted to run the examples but can't find the simulation config files in the repo. The files are on the BBP server. "/gpfs/bbp.cscs.ch/project/proj3/resources/circuits/ReleaseL2_fixed" I connected to the BBP network but can't access the directories with FTP- permission issues. Could you possibly share these files or upload them to the repo?

Ignore the monsteer warning, that's irrelevant. You can try to visualize the examples from here https://github.com/AllenInstitute/sonata/tree/master/examples. Regarding the OpenGL errors, those ones look more concerning than anything else. Can you tell me which graphics card do you have? From the errors, it looks like an integrated Intel chip. We have tested RTNeuron only with NVidia graphics cards.

@anirban6908 Did you have any chance of testing the examples I linked? By the way, I've uploaded a new AppImage that fixes some issues, I recommend you to download it again. I'm going to close this issue in the meantime because the problem originally reported is fixed. Feel free to open a new one if necessary.

Hey @hernando , Nope it's crashing when I try to load the sonata examples. Maybe it's the intel graphics card issue as you alluded. I will try the new app image. Thanks
