Python Fail to Import _DeepMimicCore #12

I get this error attempting to run mpi_run.py or any of the other python scripts.

I successfully built the wrapper as far as I know (No Build Errors) I unfortunately don't know swig or python well enough to sort this out myself and was looking for some guidance.

I usually see this issue if some of the c++ libraries are not installed. Check that you have the OpenGL, glew, and glut dll where they should be.

Phazed98 · 2018-10-19T16:55:10Z

Thanks, sorted it out. glut dll was out of place.

Thanks for sharing your code and being helpful with issues. I have a similar problem in my Ubuntu machine and cannot figure out the cause of the issue. So I wanted to ask where is the correct location for the libraries you mentioned, eg. OpenGL, glew, and glut dll, in Linux?

I am running Ubuntu 18.04 and have the following versions installed with their proper methods:

OpenGL: command "glxinfo | grep "OpenGL version" "-> shows me: OpenGL version string: 4.6.0 NVIDIA 410.79
glew: installed with make install under root user. confirmed shared objects at /usr/lib64/libGLEW.so.2.1 and /usr/lib/libGLEW.so.2.1
glut: Freeglut 3.0.0 and installed with make install. moreover tried installing with apt install freeglut3-dev package.

After all these I still get the following error even after a successful build of the wrapper:

python3 DeepMimic.py --arg_file args/kin_char_args.txt

@Phazed98 would it be possible for you to write where you found your glut dll and where you ended up putting it?

I am running the same on Linux and I got the following error. Any help would be great!!!

@IntelligentIndia7 I had the same issue first check you Glew installation.
second check your bullet installation. and Check if /usr/include or /usr/local/include has bullet file.
If the file is not available manually run gcc -I and missing files names like -lGLEW -lGL -lGLU -lglut -lBulletDynamics -lBulletCollision -lLinearMath -lm -lstdc++ to /usr/include

for me running gcc solved the issue.

IntelligentIndia7 · 2019-03-06T08:45:06Z

I had solved the above error by adding the path of libGLEW.so.2.1 to LD_LIBRARY_PATH. Now I am getting the following error. Any help regarding the same? Thanks in advance!!!!

Can some one help me with Bullet installation, I guess the problem is with Bullet.

I just ran build_cmake_pybullet_double.sh with double precision flag set off. Is that the right way or should I follow other method mentioned in Read me of Bullet with premake

bsivanantham · 2019-03-07T11:01:34Z

Check this link you might get some idea for installation https://github.com/bsivanantham/DeepMimic/blob/master/README.Install.md *Thank You* *Regards,* *Balavivek Sivanantham* *bala.ac <http://bala.ac>*

I have solved the error by Installing Bullet 2.88 instead of 2.87 and also ran command 'sudo make install' after ./build_cmake_pybullet_double.sh to overcome the linker errors to BulletDynamics and BulletCollision. Thanks for the help @bsivanantham

spodila1 · 2020-01-09T23:43:04Z

Hello I am getting the errors as some of you mention before. I did ran command 'sudo make install' after ./build_cmake_pybullet_double.sh but the problem is not be solved. Could anyone please help me on this.
