Research direction

Start with the provided jit.trace and fun.dump reproduction, then search the compiler for legalization handling of the 'MGB.ConvBias' operation. Reproduce the failure with the listed fusion options and trace where legalization stops; done means the shown model compiles successfully or the unsupported operation is reported with a clear resolution.

Description

dump代码如下
@jit.trace(symbolic=True, capture_as_const=True)
def fun(data, *, net):
pred = net(data)
return pred

fun(data, net=model)
fun.dump("test.mge", arg_names=["data"],optimize_for_inference=False, enable_fuse_conv_bias_nonlinearity=False, enable_fuse_conv_bias_with_z=False)
