Installation test failed'NameError: global name 'meshrender' is not defined' about dex-net HOT 8 CLOSED

Hi @wjydou, I got the same error. Did you end up solving this? If so what did you do? Thanks in advance!

from dex-net.

@sally-chen I reinstall the meshpy

from dex-net.

Hi @wjydou,

This may sound like a silly question, but could you please provide steps on how exactly you reinstalled meshpy?

I tried:
cd /dex-net/deps/meshpy
sudo sh install_meshrender.sh

No luck.

I have reappeared successfully. I don't know where you are wrong, and I want to see the results of your run.

from dex-net.

I got the same error. I also reinstall the meshpy but not solve it. I still set the path of meshrender.so in /etc/ld.so.conf. I tried:
cd /dex-net/deps/meshpy/meshpy

python
import meshpy
sometimes I got the error:
Unable to import meshrender shared library! Rendering will not work. Likely due to missing Boost.Numpy
Boost.Numpy can be installed following the instructions in https://github.com/ndarray/Boost.NumPy
when I changed the path of meshrender.so in ~/.bashrc, this error disappears.
However, when I tried again
cd /dex-net
epython setup.py test
The same errors occur:
File "/home/jzhang/dex-net-master/deps/meshpy/meshpy/mesh_renderer.py", line 489, in images
c, d = meshrender.render_mesh([P],
NameError: global name 'meshrender' is not defined

If so what did you do? Thanks a lot

Have you solved it, bro? I've got the same issue. Thanks a lot!

I got the same error. Reinstall meshpy are useless for me :
