i can't run the code without QCsamples

I received the same error without QC samples. I narrow down the source of this error to lines 94-97 in datasets.py. Unfortunately, simply commenting these lines leads to new errors because later visual.py expect qc_pca. It appears that in the current form tool can't be used without QC samples.

@luyiyun could you please update the NormAE, so it can be used without QC samples?
