Error in Codercises V2.2.a

Hi,

There is an error in the instruction in the original code:

Define the single and double excitations

singles, doubles = qchem.excitations(electrons=2, orbitals=qubits)

With this code you got this error:
Error: name ‘qchem’ is not defined.

Correction:
singles, doubles = qml.qchem.excitations(electrons=2, orbitals=qubits)
