Hi @josh. I found most of the [demos](https://pennylane.ai/qml/demonstrations.html) on the PennyLane website are developed using PyTorch interface but not with Tensorflow. Is there any specific reason for this? Which one do you suggest? Thank you for your time. Sincerely, Avinash ---

Hi @avinash_ch! No particular reason, it just seems that PyTorch has been more popular by people contributing demonstrations 🙂 We would love to have more tensorflow demonstrations though — if you have anything you think might make a cool demonstration, feel free to submit it as a PR to our [GitHub repo](https://github.com/XanaduAI/qml)! ---

Sure @josh. I am trying out few applications. I hope it would be useful. I will let you know once I succeed. Many thanks, Avinash.
