pre_trained model(res50)get wrong

[ljh9999]

How do you use res50 as a pre-training model?I uncompressed and renamed res50 as res101, like this:
mv resnet_v1_50.ckpt res50.ckpt
But here's the mistake:
Unable to open table file data/imagenet_weights/res50. CKPT: data loss: not an sstable (bad magic number):Perhaps your file is in a different file format and you need to use a different restore operator?
