I've followed the README, but I'm still unable to run the show3d.py example:

gs3drecon.py, line 13, in <module>
from gelsightcore import poisson_reconstruct
ImportError: cannot import name 'poisson_reconstruct' from 'gelsightcore' (unknown location)

After creating a virtual environment, I installed the package:

pip3 install . --upgrade

I've set both LD_LIBRARY_PATH and PYTHONPATH:

>>> echo $LD_LIBRARY_PATH
/home/<user>/Documents/gsrobotics/venv/lib/python3.7/site-packages/gelsightcore

>>> echo $PYTHONPATH
/home/<user>/Documents/gsrobotics/venv/lib/python3.7/site-packages/gelsightcore:/home/<user>/Documents/gsrobotics/venv/lib/python3.7/site-packages/gelsight

Using the inspect package to print the members, I get the following:

>>> print(getmembers(gelsightcore))
[('__doc__', None), ('__file__', None), ('__loader__', <_frozen_importlib_external._NamespaceLoader object at 0x7fe702c5e950>), ('__name__', 'gelsightcore'), ('__package__', 'gelsightcore'), ('__path__', _NamespacePath(['/home/<user>/Documents/gsrobotics/venv/lib/python3.7/site-packages/gelsightcore'])), ('__spec__', ModuleSpec(name='gelsightcore', loader=<_frozen_importlib_external._NamespaceLoader object at 0x7fe702c5e950>, submodule_search_locations=_NamespacePath(['/home/<user>/Documents/gsrobotics/venv/lib/python3.7/site-packages/gelsightcore'])))]

Any ideas?

It is possible that it may not work in python3.7.
It has only been tested in python3.8.
Can you use python3.8?

hmcty commented

3.8 worked. Maybe we make a note in the README?

radhen commented

Just did! Thank you. I'll close this issue now.

I'm using Ubuntu18 but I'm unable to run the show3d.py example. Have already checkout the Ubuntu18 branch and using python3.8.

This is the error:

Traceback (most recent call last):
  File "examples/show3d.py", line 11, in <module>
    from gelsight import gs3drecon
  File "/home/<user>/lib/python3.8/site-packages/gelsight/gs3drecon.py", line 13, in <module>
    from gelsightcore import poisson_reconstruct
ImportError: libIlmImf-2_3.so.24: cannot open shared object file: No such file or directory

I have updated libopenexr to the latest version by running:
sudo apt-get install libopenexr-dev

To check the versions of libopenexr, I ran:
ls /usr/lib/x86_64-linux-gnu/ | grep libIlmImf
and these are shown below:

libIlmImf-2_2.so.22
libIlmImf-2_2.so.22.0.0
libIlmImf.a
libIlmImf.so
libIlmImfUtil-2_2.so.22
libIlmImfUtil-2_2.so.22.0.0
libIlmImfUtil.a
libIlmImfUtil.so

Upon checking the Ubuntu packages (here), it seems that libIlmImfUtil-2_3.so.24 is only available in Ubuntu20? @debrashure do you have any idea why?

@hmccarty may I know if you're using Ubuntu 18?

Could you tell me the versions of the python-related tools in your Ubuntu20.04?
I am using Ubuntu20.04 in VMware Station and my python version is 3.8
other tool's version:
numpy == 1.23.4 (the requirement version is 1.17.4)
open3d == 0.13.0 (as required)
opencv_python == 3.4.16 (the requirement version is 3.4.17.61, however, I did not find this releaesd version on the Opencv website, the closet version I can find is 3.4.16)
scipy == 1.93 (the requirement version is 1.8.0)
setuptools == 45.2.0
torch==1.13.0+cu117(the requirement version is 1.8.1)
