Given groups=1, weight of size [768, 3, 16, 16], expected input[2540, 1, 1596, 1596] to have 3 channels, but got 1 channels instead

Dear authors,

Could you please help me to solve this issue?

The input to the encoder should have three channels. Usually we just repeat the channel dimension three times to make it tri-channel.
