Bug Description

when I use dynamic shape in trt, will raise error,

@narendasan can you help me slove these problem? I want to set the dynamic shape in batch size & seq_len

yjjinjie · 2024-09-09T08:37:04Z

@narendasan when to support torch_executed_modules in dynamo mode?

apbose · 2024-09-24T18:28:11Z

Hi @yjjinjie you can set the dynamic shapes and pass in the dynamic inputs using torch_tensorrt.Input
something like

compile_spec = {
    "inputs": [
        torch_tensorrt.Input(
            min_shape=(1, 3, 224, 224),
            opt_shape=(8, 3, 224, 224),
            max_shape=(16, 3, 224, 224),
            dtype=torch.half,
        )
    ],
    "enabled_precisions": enabled_precisions,
    "ir": "dynamo",
}
trt_model = torch_tensorrt.compile(model, **compile_spec)

where model is your torch trt compiled module. You can refer to the example- https://github.com/pytorch/TensorRT/blob/main/examples/dynamo/torch_compile_resnet_example.py
Since you want to set batch_size and seq_len as dynamic, you need to pass their range. eg:

        torch_tensorrt.Input(
            min_shape=(1, 1, 224, 224),
            opt_shape=(8, 2, 224, 224),
            max_shape=(16, 3, 224, 224),
            dtype=torch.half,
        )

where the first two (1, 8, 16) and (1, 2, 3) denote the batch_size and seq_len respectively. Can you try with this and see if you get the same error as above?

@apbose I use pip install --pre torch-tensorrt --index-url https://download.pytorch.org/whl/nightly/cu124 to install torch_tensorrt 2.5.0.dev20240822+cu124

then your code is correct, when do you release 2.5.0?

I cannot install pip install https://download.pytorch.org/whl/nightly/cu124/torch-2.6.0.dev20241013%2Bcu124-cp311-cp311-linux_x86_64.whl, becase of the error:

@apbose in my real code , it has another error:

when I use thetorch_tensorrt 2.5.0.dev20240822+cu124 ,
the dynamic shape: I find it encounted error when run the padding = torch.ones_like(attn_output) * (-(2**32) + 1).
the static shape is also errror: when run the scores = torch.where(sequence_mask.unsqueeze(1), attn_output, padding)

when I use torch_tensorrt 2.4.0;
the dynamic shape error is the original error
the static shape is correct

dynamic the error is:

can you help me solve this problem @apbose

when I use the nvcr.io/nvidia/pytorch:24.09-py3, then the code is ok.

torch                         2.5.0a0+b465a5843b.nv24.9
torch_tensorrt                2.5.0a0

2.5.0a0 is which day of torch_tensorrt?

but the docker image system is incompatible with my project, when to release the new version 2.5.0?

apbose · 2024-10-18T17:58:22Z

Hi @yjjinjie you can find the release wheels here- https://download.pytorch.org/whl/test/torch-tensorrt/. The torchTRT 2.5 release artifacts got pushed in officially yesterday.
As such if you want to work with the recent torchTRT changes which is torchTRT 2.6 (you can find the release version here- https://github.com/pytorch/TensorRT/blob/main/version.txt), you can work with the docker image - ghcr.io/pytorch/tensorrt/torch_tensorrt:nightly

yjjinjie · 2024-10-21T02:51:10Z

@apbose hello,when i install torch_tensorrt==2.5.0, it also has error

2.5.0a0 is which day of torch_tensorrt? can you update the version of 2.5.0? because I want to install torch_tensorrt in my project

apbose · 2024-10-21T18:26:39Z

Can you try with a new virtual env and install torch tensorrt from here- https://download.pytorch.org/whl/test/torch-tensorrt/ the wheel torch_tensorrt-2.5.0+cu124-cp310-cp310-linux_x86_64.whl. This will have torch-tensorrt 2.5 and torch 2.5. And let me know what the error is?

yjjinjie · 2024-10-22T01:18:47Z

@apbose I new a new virtual env ,and install torch_tensorrt-2.5.0+cu124-cp310-cp310-linux_x86_64.whl. it has same error .

only run:

conda create -n trt python=3.10
conda activate trt
pip install torch_tensorrt-2.5.0+cu124-cp310-cp310-linux_x86_64.whl

and run collect_env:

wget https://raw.githubusercontent.com/pytorch/pytorch/main/torch/utils/collect_env.py
python collect_env.py

yes.

in torchTRT2.4, it has the error: ValueError: len() should return >= 0

in torchTrt2.5 release , it has the error: NameError: name 's0' is not defined

apbose · 2024-10-29T19:41:55Z

Hmm so the thing is in torchTRT2.5 docker container I see it passing. It is failing in 2.4 with the error ValueError: __len__() should return >= 0. This is the output I get in 2.5 container

ok trying now, could repro the error with the additional layers. I was trying the old code before which was missing the mlp layers. The error seems to come from those.

apbose · 2024-11-07T03:07:51Z

Tried a couple of experiments
1.

seq_len_a_zero = torch.export.Dim("seq_len_a_zero", min=1, max=8196)
seq_len_b_zero = torch.export.Dim("seq_len_b_zero", min=1, max=8196)
seq_len_b_one = torch.export.Dim("seq_len_b_one", min=1, max=50)
seq_len_c_zero = torch.export.Dim("seq_len_c_zero", min=1, max=8196)
dynamic_shapes=({0:seq_len_a_zero}, {0:seq_len_b_zero, 1: seq_len_b_one}, {0:seq_len_c_zero})
exp_program = torch.export.export(model, tuple(inputs), dynamic_shapes=dynamic_shapes)
trt_gm = torch_tensorrt.dynamo.compile(exp_program, inputs)
# Run inference
out= trt_gm(*inputs)

This gives me -

 The values of seq_len_b_zero = L['args1'].size()[0] and seq_len_a_zero = L['args0'].size()[0] must always be equal.
 The values of seq_len_c_zero = L['args2'].size()[0] and seq_len_a_zero = L['args0'].size()[0] must always be equal

which means the torch export would want the seq dimension to be equal. The below

# seq_len_b_one = torch.export.Dim("seq_len_b_one", min=1, max=50)
# dynamic_shapes=({}, {1: seq_len_b_one}, {})

goes past the above but again results in

    full_default = torch.ops.aten.full.default([2, 1, s0], 1, pin_memory = False, device = device(type='cuda', index=0), dtype = torch.float32)
NameError: name 's0' is not defined

For the original case, I am trying to see how does it not encounter the torch.export issue. But it also ultimately boils down to why the s0 and s2 is undefined in the below.

 full_default = torch.ops.aten.full.default([s0, 1, s2], 1, pin_memory = False, device = device(type='cuda', index=0), dtype = torch.float32)
NameError: name 's0' is not defined

Looking into this further.

yjjinjie · 2024-11-07T03:59:19Z

@apbose yes. I also tried the dynamic_shapes too,it has the same error--NameError: name 's0' is not defined.

you can use these to solve first error The values of seq_len_b_zero = L['args1'].size()[0] and seq_len_a_zero = L['args0'].size()[0] must always be equal. use the same dim seq_len_a_zero, dynamic_shapes=({0:seq_len_a_zero}, {0:seq_len_a_zero, 1: seq_len_b_one}, {0:seq_len_a_zero})

I think you can see the difference between the trt2.5 and nvcr.io/nvidia/pytorch:24.09-py3 ,becase the nvcr.io/nvidia/pytorch:24.09-py3 trt is ok,but it has no release whl

apbose · 2024-11-07T20:51:50Z

Aah ok, thanks for pointing it out @yjjinjie . So you mean the above example passes for nvcr.io/nvidia/pytorch:24.09-py3?

apbose · 2024-11-07T21:42:03Z

Ok interesting looks like it is passing there

apbose · 2024-11-08T00:25:24Z

The issue is coming from the lowering pass replace_full_like_with_full here https://github.com/pytorch/TensorRT/blob/main/py/torch_tensorrt/dynamo/lowering/passes/replace_full_like_with_full.py where it gets the shape from the input_tensor meta data. Since this is dynamic shape, it gets s0,1,s2 which is undefined. They would be determined at runtime

yjjinjie · 2024-11-08T01:45:28Z

@apbose yes, when to fix this issue?

apbose · 2024-11-08T03:03:34Z

working on the fix will raise PR by next Monday
