KeyError: Unable to open object (object 'images' doesn't exist)

[li-pengcheng]

I am intested in your contribution, but when run your repo, there is something wrong with the FLICKR-25K.mat:
KeyError: Unable to open object (object 'images' doesn't exist)

I found that the FLICKR-25K.mat are generated automatically.

But when i download the file which your data.md mentioned, and put it under the ./data,I found it have another problem:

OSError: Unable to create file(unable to open file: name="./data/FLICKR-25K.mat",errno=17,error message='File exists', flages=15,o_flags=c2),

so could U please tell me how to run your code?
