I got a bit confused above, sorry. It is not about the `inputs` but about the `tinfos`.

Just to avoid any additional confusion I tried to print the types of the interesting variables

**conv2d\_alter\_op(attrs, inputs, tinfos, out\_type)**

```auto
print(type(inputs[0]))
# <class 'tvm.relay.expr.Var'>

print(type(tinfos[0]))
# <class 'tvm.te.tensor.Tensor'>

```

**\_qnn\_conv2d\_legalize\_arm\_cpu(attrs, inputs, types)**

```auto
print(type(inputs[0]))
# <class 'tvm.relay.expr.Var'>
print(type(types[0]))
#<class 'tvm.ir.tensor_type.TensorType'>

```

The call to `relay.backend.compile_engine.select_implementation` asks to provide an array of `tvm.te.Tensor`s as its 3rd argument while I have (during legalization) only a `tvm.ir.TensorType` array.

So, the question still remains: is there a way to get a tensor during legalization?
