Potty training help 2.5 year old

So my 2.5 y/o will tell me when she is pooping and when she is pottying in her diaper. I am trying to potty train her but she is crying every time I put her on the big potty. She will sit there if I distract her but not for too long. The thing is she is now taking off her diapers and then will be running around without a diaper. So I’m at a loss. Do I keep potty training her or hold off?
