**python examples/demo.py --model-folder /home/lxz/mygrade2/smplx/smplx/models/ --plot-joints=True --gender="neutral"
SMPLX(
Gender: NEUTRAL

Flat hand mean: False
Number of Expression Coefficients: 10
(vertex_joint_selector): VertexJointSelector()
)

@Lixz123456 Where are you running this? It seems like pyrender is not able to open a window to display the results.
