在加载onnx模型时报错，代码如下 import onnx

import numpy as np

import onnxruntime as ort

import tvm

from tvm import relay

from tvm.relay.import_model import import_model_to_igie

加载模型

model_path = ‘/gptsovits/sovits_infer/date/t2s_first_stage_decoder_simp.onnx’

model = onnx.load(model_path)

创建 InferenceSession，验证模型

try:

session = ort.InferenceSession(model_path, providers=['CPUExecutionProvider'])

print("InferenceSession 创建成功。")

except Exception as e:

print(f"创建 InferenceSession 失败: {e}")

exit(1)

测试输入

input_data = {

'all_phoneme_ids': np.zeros((1, 64), dtype=np.int64),

'bert': np.zeros((1, 1024, 64), dtype=np.float32),

'prompt': np.zeros((1, 64), dtype=np.int64),

'top_k': np.array([5], dtype=np.int64),

'temperature': np.array([1.0], dtype=np.float32)

}

运行推理

try:

outputs = session.run(None, input_data)

print("ONNX 推理成功，输出:", outputs)

except Exception as e:

print(f"推理失败: {e}")

exit(1)

备用：使用标准 ONNX 导入

print(“正在导入模型（标准 ONNX 导入）…”)

try:

shape_dict_standard = {

    'all_phoneme_ids': (1, 64),

    'bert': (1, 1024, 64),

    'prompt': (1, 64),

    'top_k': (1,),

    'temperature': (1,)

}

mod, params = relay.frontend.from_onnx(model, shape_dict_standard)

print("✅ 模型导入成功（使用标准 ONNX 导入）。")
