part7a_bitstream still using vivado_hls?

[DrBwts]

I'm using the Vitis branch of the tutorials but it looks like tutorial 7a is still using the Vivado HLS back end which is no longer available in the latest Vivado releases.

In cell 7,
hls_model.build(csim=False, export=True, bitfile=True)

Which throws the following error,
