AttributeError: module 'jax.core' has no attribute 'ConcreteArray' - Problems using jax.grad(circuit)

Hi @Kiran_Kumar_M , welcome to the Forum!

For now I’d recommend installing JAX 0.4.33 on Google Colab. For example the line below installs PennyLane and JAX v0.4.33.

!pip install pennylane jax==0.4.33

If you already have a session running you may need to restart it after running the install (in the “Runtime” menu).

Let us know if this works for you!
