Divide by zero error

[Zevrap-81]

I am getting this error when i am running the example described in the readme file

ZeroDivisionError: division by zero

[lingtengqiu]

could you give me more details about source_bo.shape[0]. I guess the error is may source_bo be zero tensor?

I ran the same thing again, but I did not get the error. Only the run time is really slow.

[lingtengqiu]

The NICP is a optimization-based method, which needs some time to fit. However, it only runs once, after that, you do not run it NICP again!

This time i got this error "unwished error n_inv_mask:(1:10000)" error

[lingtengqiu]

This is not the error, is a warning. It means, some transformation matrix can not be inverse.

This time i got this error "unwished error n_inv_mask:(1:10000)" error
