Generate test images with different batch size fails

Hello,
I am new to tensorflow itself.
I trained the CelebA dataset with a batch size of 64. But, when I was testing it with different batch size it fails like following,
[*] Failed to find a checkpoint
Exception: [!] Train a model first, then run test mode
For test mode also, I need to give a batch size of 64?

Start by reproducing the reported failure in test mode after training CelebA with batch size 64, then retry with a different batch size. Trace the checkpoint lookup and the "Train a model first" path; done means the supported test-mode batch-size behavior is identified and the failure is corrected or clearly documented.
