AttributeError: module ‘tvm.relay’ has no attribute ‘ir_pass’

from tvm import relay def make_dataset(graph, size=100): args = relay.ir_pass.infer_type(graph).params def create_arr(var): ttype = var.type_annotation np_arr = np.random.uniform(-1.0, 1.0, size=ttype.concrete_shape).astype(ttype.dtype) return tvm.ndarray.array(np_arr) n, c, h, w = 1, 3, 224, 224 def make_graph(data): weight = relay.var(“conv_weight”) out = relay.nn.conv2d(data, weight, kernel_size=(3, 3), padding=(1, 1), channels=c) out = relay.Function(relay.ir_pass.free_vars(out), out)

Anyone can solve this problem?

#2 
import tvm
from tvm import relay
import tvm.relay.testing
from tvm.relay.expr_functor import ExprMutator

class ScheduleConv2d(ExprMutator):
    def __init__(self, device):
        self.device = device
        super().__init__()

    def visit_call(self, expr):
        visit = super().visit_call(expr)
        if expr.op == tvm.relay.op.get("nn.conv2d"):
            return relay.annotation.on_device(visit, self.device)
        else:
            return visit

# def schedule_conv2d_on_gpu(expr):
#     sched = ScheduleConv2d(tvm.gpu(0))
#     return sched.visit(expr)

def schedule_conv2d_on_gpu(expr):
    sched = ScheduleConv2d(tvm.cpu(0))
    return sched.visit(expr)

resnet, params = relay.testing.resnet.get_workload()
print(resnet)
# resnet = schedule_conv2d_on_gpu(resnet)
# print(resnet)
resnet = relay.ir_pass.rewrite_annotated_ops(resnet, 0)
print(resnet)

This is a another case…
