When executing

from qat.lang.AQASM import Program, H, CNOT

# Create a Program
qprog = Program()
# Number of qbits
nbqbits = 2
# Allocate some qbits
qbits = qprog.qalloc(nbqbits)

# Apply some quantum Gates
qprog.apply(H, qbits[0]) 
qprog.apply(CNOT, qbits[0], qbits[1])

# Export this program into a quantum circuit
circuit = qprog.to_circ()
# And display it!
circuit.display()

the error is
