Hello, could you please tell me how to generate such data set through this code? I already have the 3D model as follows. I will show that there is no package bpy

Did you successfully run this install script with test? https://github.com/DIYer22/bpycv#-install

# Check bpycv ready
./blender -b -E CYCLES --python-expr "import bpycv,cv2;d=bpycv.render_data();bpycv.tree(d);cv2.imwrite('/tmp/try_bpycv_vis(inst-rgb-depth).jpg', d.vis()[...,::-1])"

yes，this test is running successfully!

It's look fine. try:

mkdir ycb_demo
cd ycb_demo/

# prepare code and example data
git clone https://github.com/DIYer22/bpycv
git clone https://github.com/DIYer22/bpycv_example_data

cd bpycv/example/

blender -b -P ycb_demo.py

cd dataset/vis/
ls .  # visualize result here
# 0.jpg

when i run the "blender -b -P ycb_demo.py", it said the error for this (Command 'blender' not found, but can be installed with:

sudo snap install blender # version 3.4.0, or sudo apt install blender

See 'snap info blender' for additional versions. )

[DIYer22]

try replace blender to ./blender -b -P ycb_demo.py in Blender dir

[lxwkobe24]

try replace blender to ./blender -b -P ycb_demo.py in Blender dir

yes ,it's finish! But i want to use myself the 3D model to create dataset like this: i really hope you could tell me how to realize ! thanks

First, learn basic Blender Python API. Than fellow this script, it has comment, https://github.com/DIYer22/bpycv/blob/master/example/ycb_demo.py
