I'd maybe wait a few months, then try again. The trick with my daughter was to buy one of those dolls that can "drink" a bottle. Take a day or weekend where you take her to buy the "doll" and some panties for your daughter. Give the doll a name. Go home and show her how the doll has big girl panties on. Then give her the bottle filled with water and sit her on the potty. Show her that she didn't wet her panties. (my husband even got creative, and baked brownies and used pieces of those for #2 - ha ha -I've never looked at a brownie the same since) We told my daughter that she could be like her doll, and for whatever reason, it worked. She was potty trained in a weekend. She did have a few accidents here and there, but no more diapers. She did wear pull ups at night until she was 4, but we went through maybe 1 package. Once they get it, throw the diapers out or donate them. Out of sight, out of mind. Also, let her clean up her own accidents. Don't berate her, just say "oops you had an accident, I'll get you some new panties while you take those wet ones off and put them on the washing machine". She'll get sick of doing that real quick, because they don't want to touch it. You might have to help her if it's an accident with #2, but I'd still let her do most of the clean up.
Does your daughter go to preschool? If so, maybe her teachers could reinforce it at school to help you. Usually by the time a toddler turns 3, most schools work with the parents on potty training.
Good luck! My daughter loved her diapers too. My son was easy - potty trained in a day by my husband. He's the potty whisperer. :)
