Intro

Hi!

I am a graduate.

My setup

My mujoco version is 2.3.7

My question

My code is listed as follows:

xml = """
<mujoco>
  <worldbody>
    <light name="top" pos="0 0 1"/>
    <body name="box_and_sphere" euler="0 0 -30">
      <joint name="swing" type="hinge" axis="1 -1 0" pos="-.2 -.2 -.2"/>
      <geom name="red_box" type="box" size=".2 .2 .2" rgba="1 0 0 1"/>
      <geom name="green_sphere" pos=".2 .2 .2" size=".1" rgba="0 1 0 1"/>
    </body>
  </worldbody>
</mujoco>
"""
model = mujoco.MjModel.from_xml_string(xml)
data = mujoco.MjData(model)

# enable joint visualization option:
scene_option = mujoco.MjvOption()
scene_option.flags[mujoco.mjtVisFlag.mjVIS_JOINT] = True

duration = 3.8  # (seconds)
framerate = 60  # (Hz)

# Simulate and display video.
frames = []
mujoco.mj_resetData(model, data)
with mujoco.Renderer(model) as renderer:
  while data.time < duration:
    mujoco.mj_step(model, data)
    if len(frames) < data.time * framerate:
      renderer.update_scene(data, scene_option=scene_option)
      pixels = renderer.render()
      frames.append(pixels)

media.show_video(frames, fps=framerate,codec='gif')

And an error occurs.

AttributeError Traceback (most recent call last)
Cell In[3], line 26
24 frames = []
25 mujoco.mj_resetData(model, data)
---> 26 with mujoco.Renderer(model) as renderer:
27 while data.time < duration:
28 mujoco.mj_step(model, data)

AttributeError: enter

Minimal model and/or code that explain my question

If you encountered the issue in a complex model, please simplify it as much as possible (while still reproducing the issue).

Model:

minimal XML

<mujoco>
  <worldbody>
    <light pos="0 0 1"/>
    <geom type="sphere" size="1" rgba="1 0 0 1"/>
  </worldbody>
</mujoco>

Code:

import mujoco
import mediapy as media
model = mujoco.MjModel.from_xml_string(xml)
data = mujoco.MjData(model)

with mujoco.Renderer(model) as renderer:
  mujoco.mj_forward(model, data)
  renderer.update_scene(data)

  media.show_image(renderer.render())
