No module named 'bop_toolkit_lib'

Describe the issue

when I try to use bproc.loader.load_bop_intrinsics(), this error occurs, before that I have run "blenderproc pip install bop_toolkit", and downloarded successfully. How to fix it?

Minimal code example

import blenderproc as bproc
import bpy
import os
import numpy as np

# 初始化Blenderproc
bproc.init()

# 设置输出路径
output_dir = "output"
os.makedirs(output_dir, exist_ok=True)

# 加载物体（示例：加载一个cube）
obj = bproc.loader.load_obj("/home/zhangsijin/new_func/modules/obj_01.ply")

# 加载相机内参
bproc.loader.load_bop_intrinsics("/home/zhangsijin/new_func/camera.json")

# 创建光源
# 平面光源（天花板位置）
light_plane = bproc.object.create_primitive('PLANE', scale=[3, 3, 1], location=[0, 0, 10])  # 创建一个大平面作为天花板光源
light_plane.set_name('light_plane')  # 命名光源平面
light_plane_material = bproc.material.create('light_material')  # 创建光源材质
# 点光源
light_point = bproc.types.Light()  # 创建点光源
light_point.set_energy(200)  # 设置点光源能量（亮度）

# 设置渲染参数
bproc.renderer.set_max_amount_of_samples(50)
bproc.renderer.set_noise_threshold(0.01)
bproc.renderer.set_cpu_threads(0)

# 启用Alpha通道以去除背景
bproc.renderer.set_output_format(enable_transparency=True)

# 渲染图像
data = bproc.renderer.render()

# 渲染深度图（用于姿态计算）
depth = bproc.renderer.render_depth()

# 保存图像
bproc.writer.write_hdf5(output_dir, data)
bproc.writer.write_depth(output_dir, depth, file_format="exr")

# 获取物体姿态信息
for obj in bproc.filter.all_objects():
    if obj.get_cp("is_from_loaded_obj"):
        # 获取世界矩阵（包含位置和旋转信息）
        world_matrix = obj.get_local2world_mat()
        print(f"Object: {obj.get_name()}")
        print(f"World Matrix:\n{world_matrix}")
        
        # 提取位置和四元数旋转
        position = world_matrix.to_translation()
        rotation = world_matrix.to_quaternion()
        
        # 保存姿态信息到文件
        with open(os.path.join(output_dir, "poses.txt"), "a") as f:
            f.write(f"{obj.get_name()}: {position} {rotation}\n")

print(f"渲染完成，结果保存在: {output_dir}")

Hey @ZsjSpace

the bop toolkit needs to be installed in blenders python environment not the python environment you are using outside.

You can install it via

bproc pip install git+https://github.com/thodan/bop_toolkit
