I have saved the predicted flow with shape [batch=1,3,npoints=8192] as follows:
flow=flow.cpu().detach().numpy #convert tensor to numpy file
np.save(file_path,flow)
then, in visual.py I have tried to upload the saved file with the same code as in visual.py but the shape of the flow is zero
could you explain how could I solve this problem please ..

thanks in advance
