Hi @lhutton1 , thanks for your contributition.
After running FuseOps pass, I want to get the memory usage per op or per
primitive func by `AnnotateUsedMemory` pass for furture optimization. I get a
resnet18 ir model, then put it as the input IRModule of `AnnotateUsedMemory`
pass. The output IRModule has no `used_memory` attr. Test code as follow:
```python
import pytest
from collections import OrderedDict
import numpy as np
import tvm
from tvm import relay
from tvm.relay import testing
def AnnotateUsedMemory():
return relay.transform._ffi_api.AnnotateUsedMemory()
def _get_data(in_data_shapes, dtype="float32"):
in_data = OrderedDict()
for name, shape in in_data_shapes.items():
in_data[name] = np.random.uniform(size=shape).astype(dtype)
return in_data
def _run_relay(mod, params, in_data, pass_enabled):
target = "llvm"
dev = tvm.device("llvm", 0)
in_data = [tvm.nd.array(value) for value in in_data.values()]
if pass_enabled:
mod = relay.transform.InferType()(mod)
mod = relay.transform.ToANormalForm()(mod)
mod = relay.transform.InferType()(mod)
mod = AnnotateUsedMemory()(mod)
# create primitive functions
mod = relay.transform.FuseOps()(mod)
print(f'\nmod when AnnotateUsedMemory is {pass_enabled}:\n {mod}')
out_data = relay.create_executor(
"graph", mod, device=dev, target=target).evaluate()(*in_data,
**params)
return out_data.numpy()
def _verify_results(mod, params, in_data, rtol=1e-5, atol=1e-5):
before = _run_relay(mod, params, in_data, False)
after = _run_relay(mod, params, in_data, True)
np.testing.assert_allclose(before, after, rtol, atol)
def test_resnet():
num_class = 1000
in_data_shapes = OrderedDict({"data": (1, 3, 224, 224)})
in_data = _get_data(in_data_shapes, dtype="float32")
for n in [18]: # 18, 34, 50, 101
mod, params = tvm.relay.testing.resnet.get_workload(
batch_size=1, num_classes=num_class, num_layers=n)
_verify_results(mod, params, in_data)
if __name__ == "__main__":
pytest.main([__file__])
```
I am not familar with `AnnotateUsedMemory` pass. Could memory usage per op
or per primitive func be gotten by your pass? If not, how to get it based on
your pass? Thanks in advance ^_^
