Other camera list fail to achieve low MPJPE

[jiku100]

Hello, I'm trying to test this model with another camera list.

The default camera list consists of 12, 6, 23, 13, and 3 camera indexes.
In that case, It achieves an average MPJPE of 16.20667, and detection fails of 0 / 1000.

However, when I change the viewpoint to 0, 1, 16, 21, 28,
It reports an average MPJPE of 2703.57132, and detection fails of 684 / 1000.

So, Is this model only available to trained viewpoints?
