Always loads first checkpoint, won't read others.

Hey,
Thanks a lot for this model, I tried successfully to generate images at different resolutions and I am happy with it. While doing this I generated several checkpoints folder for different resolutions that are present in the _checkpoint_ folder.

However, when I try to load a former model and restore one of the checkpoints with this command:
`$ python main.py --dataset --input_height= --crop
`
It launches, load a checkpoint but produce samples from the first ever model I created, which is super low res, no matter the input_height or output_height I specify. I am pretty sure it keeps loading from the first ever checkpoint folder created.

I tried to delete the checkpoint that is launched but it won't recognise any other. I tried changing the name of the checkpoint folder I want to load to the one that is launched but it gives me this error:

`"InvalidArgumentError (see above for traceback): Restoring from checkpoint failed. This is most likely due to a mismatch between the current graph and the graph from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint."`

In other words, I want to load a checkpoint that is in a folder images_64_512_512 but it keeps loading the folder image_64_64_64

I'm not sure how to change this, if you have any ideas or pointers, they are welcome.
