AttributeError: module 'mujoco' has no attribute 'viewer'

Intro

Hi!

I am a undergrad student , I use MuJoCo for my research on iiwa.

My setup

MuJoCo Python package version: 3.3.6
MuJoCo C library version: 3.3.6

My question

AttributeError: module 'mujoco' has no attribute 'viewer'
I run the project in the Vmware. It shows the problem. And i have no idea.

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


xml_path = "/home/let/MujocoTutorials/robot/robot_arms/kuka_iiwa_14/iiwa14.xml"


model = mujoco.MjModel.from_xml_path(xml_path)
data = mujoco.MjData(model)
with mujoco.viewer.launch_passive(model, data) as viewer:
    while viewer.is_running():
        mujoco.mj_step(model, data)
        viewer.sync()

Confirmations

• I searched the latest documentation thoroughly before posting.
• I searched previous Issues and Discussions, I am certain this has not been raised before.

I think you should just first import it as from mujoco import viewer and then call viewer.launch_passive(model, data)

Thank you very much. I've made a silly mistake. Wish you happy!
