How to use the fine tuned model to predict multiple samples in the mmpretrain framework?

[yuekejuan]

I have fine tuned a image classification model (epoch_100.pth) based on resnet50, i use image_demo.py, it can only predict one image at a time, and the predicted result is output as image.
(1)how can i use it to predict 100 samples without annotation
(2)how can i save the predict result as .csv file.
