Not sure if Tensorflow savedmodel is any different, but I use this code to convert my TF savedmodels to ONNX:
import tensorflow as tf
import tf2onnx
input_path = "../data/models/"
model_name = "simple_upsampler_bilinear"
file_type = ''
output_path = "../data/models/onnx_models/"
#load the model.
pre_model = tf.keras.models.load_model(input_path + model_name + file_type)
# Convert h5 to onnx.
tf2onnx.convert.from_keras(pre_model, output_path = output_path + model_name + ".onnx", opset = 9)
from barracuda-release.
ONNX is required. You can convert a PyTorch saved model to ONNX like shown below. I include the ONNX checker, it should confirm everything worked:
import torch
import torch.onnx
import onnx
import numpy as np
# load path
load_path = r"your/model/directory/name_of_model.pt"
# output path
output_path = r"your/output/directory/name_of_model.onnx"
model = torch.load(load_path)
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)
model.eval()
# Input to the model (you need to define the size for the model inputs)
# This example is for a single batch, single channel tensor of size 28 x 28)
x = torch.randn(1, 1, 28, 28, requires_grad=True).to(device)
torch_out = model(x)
# Export the model
torch.onnx.export(model, # model being run
x, # model input (or a tuple for multiple inputs)
output_path, # where to save the model (can be a file or file-like object)
export_params=True, # store the trained parameter weights inside the model file
opset_version=9, # the ONNX version to export the model to
do_constant_folding=True, # whether to execute constant folding for optimization
input_names = ['input'], # the model's input names
output_names = ['output'], # the model's output names
)
onnx_model = onnx.load(output_path)
onnx.checker.check_model(onnx_model)
from barracuda-release.
