Thank you @TylerGubala
Is this warning I should fix?
WARN (bgl): source/blender/python/generic/bgl.c:2654 BPyInit_bgl: 'bgl' imported without an OpenGL backend. Please update your add-ons to use the 'gpu' module. In Blender 4.0 'bgl' will be removed.

@TylerGubala I also got this error:

These are the packages imported by the author:

import os
import sys
import yaml
import torch
import math
import numpy as np
import cv2
from tqdm import tqdm
import json
import trimesh
import argparse
import glob
import pickle
from tqdm import trange
from bpy_render import render_ply
from pytorch3d.transforms import euler_angles_to_matrix, matrix_to_euler_angles, rotation_6d_to_matrix

I see there is bpy_render.

What do you think?

Can you do these steps to see if you can reproduce the error?

git clon ehttps://github.com/sailor-z/Unseen_Object_Pose.git
cd UnseenObjectPose
conda create -n testbpy python=3.10 anaconda
 conda activate testbpy
pip install bpy==3.5.0
conda install pytorch=1.13.0 torchvision pytorch-cuda=11.6 -c pytorch -c nvidia
conda install -c fvcore -c iopath -c conda-forge fvcore iopath
git clone https://github.com/facebookresearch/pytorch3d.git
cd pytorch3d && pip install -e .
cd ..
cd Render
(testbpy) mona@ard-gpu-01:~/Unseen_Object_Pose/Render$ python data_generation.py

as you see they are using bpy

sailor-z/Unseen_Object_Pose#6
I have CUDA 11.6

monajalal commented

They have a render_objects method defined in the same level as the other python code is. It seems an import error in Python 3.10?

import pyrender
import numpy as np
import cv2

def render_objects(meshes, ids, poses, K, w, h):
    assert(K[0][1] == 0 and K[1][0] == 0 and K[2][0] ==0 and K[2][1] == 0 and K[2][2] == 1)
    fx = K[0][0]
    fy = K[1][1]
    cx = K[0][2]
    cy = K[1][2]
    objCnt = len(ids)
    assert(len(poses) == objCnt)

    # set background with 0 alpha, important for RGBA rendering
    scene = pyrender.Scene(bg_color=np.array([0.0, 0.0, 0.0, 1.0]), ambient_light=np.array([0.02, 0.02, 0.02, 1.0]))
    # pyrender.Viewer(scene, use_raymond_lighting=True)
    # camera = pyrender.PerspectiveCamera(yfov=np.pi / 3.0, aspectRatio=1.0)
    camera = pyrender.IntrinsicsCamera(fx=fx,fy=fy,cx=cx,cy=cy,znear=0.05,zfar=100000)
    camera_pose = np.eye(4)
    # reverse the direction of Y and Z, check: https://pyrender.readthedocs.io/en/latest/examples/cameras.html
    camera_pose[1][1] = -1
    camera_pose[2][2] = -1
    scene.add(camera, pose=camera_pose)
    #light = pyrender.SpotLight(color=np.ones(3), intensity=4.0, innerConeAngle=np.pi/16.0, outerConeAngle=np.pi/6.0)
    light = pyrender.DirectionalLight(color=np.ones(3), intensity=4.0)
    #light = pyrender.PointLight(color=np.ones(3), intensity=4.0)
    scene.add(light, pose=camera_pose)
    for i in range(objCnt):
        clsId = int(ids[i])
        mesh = pyrender.Mesh.from_trimesh(meshes[clsId])
        H = np.zeros((4,4))
        H[0:3] = poses[i][0:3]
        H[3][3] = 1.0
        scene.add(mesh, pose=H)
    # pyrender.Viewer(scene, use_raymond_lighting=True)

    r = pyrender.OffscreenRenderer(w, h)
    # flags = pyrender.RenderFlags.OFFSCREEN | pyrender.RenderFlags.DEPTH_ONLY
    #flags = pyrender.RenderFlags.OFFSCREEN
    #flags = pyrender.RenderFlags.OFFSCREEN | pyrender.RenderFlags.RGBA
    #color, depth = r.render(scene, flags=flags)
    color, depth = r.render(scene)

    color = cv2.cvtColor(color, cv2.COLOR_RGB2BGR) # RGB to BGR (for OpenCV)
    #color = cv2.cvtColor(color, cv2.COLOR_RGBA2BGRA) # RGBA to BGRA (for OpenCV)

    return color, depth

It is in py_render.py

I also have no problem importing the following

I got it fixed.

I added
from py_render import render_objects
in
data_generation.py
and
also installed
pip install pyrender
