I was able to fix the implementation issues and convert the model to ONNX: https://github.com/ibaiGorordo/ONNX-CREStereo-Depth-Estimation. From there it should be easier to convert to other platforms. Here is a video with the output in ONNX: https://youtu.be/ciX7ILgpJtw
@sunmooncode regarding the low speed, if you use a low resolution (320x240) and only do one pass without flow_init, you can get decent speed with good quality.

@sunmooncode
I have slightly modified the inference code in the repository provided by ibaiGorordo to make ONNX exportable logic.
https://github.com/ibaiGorordo/CREStereo-Pytorch
It is important to note that it takes 30 minutes to an hour to output a single onnx file.
device = 'cpu'
model = Model(max_disp=256, mixed_precision=False, test_mode=True)
model.load_state_dict(torch.load(model_path), strict=True)
model.to(device)
model.eval()

MODEL = f'crestereo_{MODE}_iter{ITER}'
for H, W in RESOLUTION:
if MODE == 'init':
onnx_file = f"{MODEL}_{H}x{W}.onnx"
x1 = torch.randn(1, 3, H, W).cpu()
x2 = torch.randn(1, 3, H, W).cpu()
torch.onnx.export(
model,
args=(x1,x2),
f=onnx_file,

)
model_onnx1 = onnx.load(onnx_file)
model_onnx1 = onnx.shape_inference.infer_shapes(model_onnx1)
onnx.save(model_onnx1, onnx_file)
model_onnx2 = onnx.load(onnx_file)
model_simp, check = simplify(model_onnx2)
onnx.save(model_simp, onnx_file)
elif MODE == 'next':
onnx_file = f"{MODEL}_{H}x{W}.onnx"
x1 = torch.randn(1, 3, H, W).cpu()
x2 = torch.randn(1, 3, H, W).cpu()
x3 = torch.randn(1, 2, H//2, W//2).cpu()

import sys
sys.exit(0)
Next, this script
https://github.com/PINTO0309/PINTO_model_zoo/blob/main/284_CREStereo/onnx_merge.py
Alternatively, merging onnx into a single graph using this tool is optional and feasible.
https://github.com/PINTO0309/snc4onnx
from crestereo.
I have committed a large number of ONNX models of various resolution and ITER combinations. I imagine the ITER10 version is twice as fast.
https://github.com/PINTO0309/PINTO_model_zoo/tree/main/284_CREStereo
-
init - ITER 2,5,10,20
This model generatesflow_init
. -
next - ITER 2,5,10,20
This model takes as input a total of three images:flow_init
generated by the init model and two LEFT/RIGHT images. -
combined - ITER 2,5,10,20
Two levels of inference,init
andnext
, are merged into a single onnx.

@sunmooncode So far I was able to convert to traced module using the following code:
import numpy as np
import megengine.functional as F
from megengine import jit
import megengine.traced_module as tm
import megengine as mge
from nets import Model
print(mge.__version__)
data1 = mge.tensor(np.random.random([1, 3, 480, 640]).astype(np.float32))
data2 = mge.tensor(np.random.random([1, 3, 480, 640]).astype(np.float32))
pretrained_dict = mge.load("crestereo_eth3d.mge")
model = Model(max_disp=256, mixed_precision=False, test_mode=True)
model.load_state_dict(pretrained_dict["state_dict"], strict=True)
model.freeze_bn()
output = model(data1,data2)
print(output)
traced_model = tm.trace_module(model, data1, data2)
traced_model.eval()
mge.save(traced_model, "traced_model.tm")
Running it will give you an error, but you can fix it by commenting this line:
Line 45 in 924d9f2
My idea is to see if the tracedmodule_to_onnx
function in the mgeconverter will work. However, when I try to convert the model, I get the following error:
tm_to_onnx.py", line 51, in tracedmodule_to_onnx
traced_module = mge.load(traced_module)
File "/usr/local/lib/python3.7/dist-packages/megengine/serialization.py", line 107, in load
return load(fin, map_location=map_location, pickle_module=pickle_module)
File "/usr/local/lib/python3.7/dist-packages/megengine/serialization.py", line 112, in load
return pickle_module.load(f)
ValueError: unsupported pickle protocol: 5
For some reason in that machine, loading the model does not work, but in another machine I have, I am able to do traced_module = mge.load(traced_module)
without any issue. However in that machine I am not able to install mgeconverter . So I will keep trying tomorrow.

@ibaiGorordo thanks for your help!
When I use mgeconvert's convert tracedmodule_to_onnx -i tracedmodule.tm -o out.onnx I get the following error:

AssertionError: METHOD __rmul__ is not supported.
The reason is that many OPs of CREstereo do not have corresponding operator support for mgeconverter.
In addition:
When I use the script to evaluate the real-time performance of CREstereo, my computer is an RTX1050ti, and the result is less than 1 Fps. However, under the same conditions, RAFTstereo has nearly 3 Fps, and the realtime model has more than 6 Fps. So CRestereo is too big for me.

I get segmentation fault even if I build megengine and megconvert for my environment.

Commenting these two lines fixes the rmul error:

However, next I get the following error:
AssertionError: Module <class 'megengine.module.normalization.InstanceNorm'> is not supported.
from crestereo.
That is because megconvert does not support this operation. I have seen that many in the network do not support it, so it should not be converted.
from crestereo.
Since it seems to be hard to convert, I have tried to implement the model in Pytorch. The model seems to run normally, but since I don't have the weights I cannot fully test it.
My hope is that somehow we can translate the weights from this model there.

Hi @PINTO0309 thanks for the tip. @sunmooncode I got the same error after fixing my issue.
Also I have create a Google Colab notebook to reproduce the error:
https://colab.research.google.com/drive/1IMibaByKwiAIam8UAvyI-2U_Z9O7rBWS?usp=sharing
Because of the CUDA version, it crashed if I load the model with a runtime with GPU. So, run it without GPU.
from crestereo.
Yeah... I tried converting the model to .mge (using @trace(symbolic=False, capture_as_const=True
), but using mge_to_onnx outputs the following error: AssertionError: OP PowC is not supported
(I updated the Google Colab notebook).
I do not understand the framework enough, but seems to be hard to fix the issues
from crestereo.
@ibaiGorordo Good job
You can train a model with a small step count and run through that model to see if it converts. Secondly, pytorch to onnx cannot contain dynamic structures. The structure needs to be instantiated.
from crestereo.
@sunmooncode I was able to convert the weights directly, however, it seems that there is some parameter in my Pytorch implementation that is probably not correct. But overall the conversion seems to work.
Haven't tried converting it to other frameworks yet.
from crestereo.
@PINTO0309 @ibaiGorordo Thanks for your help!
I would like to know how you converted these models, can you provide their conversion scripts, it would be very helpful to me.
from crestereo.
@PINTO0309 I have a problem that onnx has a hard time handling logical operators, but there are a lot of "if" constructs in the model. Does this have any effect on the transformation of the model?

Hi @PINTO0309 Thanks a lot for the great work! I have a question here. Your CREStereo model zoo contains two types of ONNX files. One is ONNX, and the other is TensorRT (also in .onnx format). Do you mind sharing how the TensorRT ONNX files were generated? Thanks!

The topic is too old and I no longer have the resources at hand from that time. However, a comparison will immediately reveal the difference. You will soon see what errors you get when you run it on TensorRT.
