ModuleNotFoundError: No module named 'pybullet_engine'

Hello. I was following the setting-up steps to see how Diffusion-CCSP works. But I got an error at the following step:
- Compile IK for Franka Panda if want to collect and test robot planning.
(cd pybullet_engine/ikfast/franka_panda; python setup.py)
This is the log shown in terminal:
(diffusion-ccsp) user@user-ThinkPad-P16-Gen-1:~/test_ws/diffusion-ccsp/pybullet_engine/ikfast/franka_panda$ python setup.py
Traceback (most recent call last):
File "/home/user/test_ws/diffusion-ccsp/pybullet_engine/ikfast/franka_panda/setup.py", line 13, in
from pybullet_engine.ikfast.compile import compile_ikfast
ModuleNotFoundError: No module named 'pybullet_engine'
If I run python pybullet_engine/ikfast/franka_panda/setup.py
directly from the /diffusion-ccsp
directory, it will give the following error:
pybullet build time: Oct 14 2023 15:48:24 Traceback (most recent call last): File "/home/yanni/test_ws/diffusion-ccsp/pybullet_engine/ikfast/franka_panda/setup.py", line 13, in from pybullet_engine.ikfast.compile import compile_ikfast File "/home/yanni/test_ws/diffusion-ccsp/pybullet_engine/init.py", line 16, in from .client import * File "/home/yanni/test_ws/diffusion-ccsp/pybullet_engine/client.py", line 23, in import jacinle ModuleNotFoundError: No module named 'jacinle'
So I added a line export PYTHONPATH=./Jacinle:$PYTHONPATH
in the setup.sh file and sourced it, then it's like:
pybullet build time: Oct 14 2023 15:48:24 gcc: error: ikfast_panda_arm.cpp: No such file or directory gcc: fatal error: no input files compilation terminated. error: command '/usr/bin/gcc' failed with exit code 1
I think I already did everything mentioned in the previous steps. I cloned the Jacinle repo into /diffusion-ccsp
. Did I miss anything or is the code still in development?
Thank you.
On your last solution. change the setup.py code to:
def main():
robot_name = 'panda_arm'
compile_ikfast(
module_name='ikfast_{}'.format(robot_name),
cpp_filename='./pybullet_engine/ikfast/franka_panda/ikfast_{}.cpp'.format(robot_name),
remove_build=True
)
Then it works:
ikfast module ikfast_panda_arm imported successful
