Issues with Rendering - no attribute 'glfwGetCurrentContext'

[varungupta31]

I am new to this benchmark and tool.

I installed as per the documentation

pip install git+https://github.com/Farama-Foundation/Metaworld.git@master#egg=metaworld

And tried the started code,

import metaworld
import random

print(metaworld.ML1.ENV_NAMES)  # Check out the available environments

env_name = 'basketball-v2' # Pick an environment name

render_mode = 'human' # set a render mode

ml1 = metaworld.ML1(env_name) # Construct the benchmark, sampling tasks

env = ml1.train_classes[env_name](render_mode=render_mode)
task = random.choice(ml1.train_tasks)
env.set_task(task)  # Set task

obs = env.reset()  # Reset environment
a = env.action_space.sample()  # Sample an action
obs, reward, terminate, truncate, info = env.step(a)

I run into this error,

Exception ignored in: <function WindowViewer.__del_ at 0x10724c310>

AttributeError: 'NoneType' object has no attribute 'glfwGetCurrentContext'

A similar error was observed on Ubuntu 20.04, with the same setup instruction and code.

Kindly help,
Thanks.

That's not an error that causes problems, it happens when your script ends without explicitly calling env.close()

Thanks, figured that out ... rookie mistake 🫠
