调研方向

从 onnxscript/_internal/ast_utils.py 和 onnxscript/main.py 开始，重点关注 get_src_and_ast 以及为 conv 抛出错误的装饰器路径。在 PyCharm 的动态编译控制台和 .venv 中重现该示例，然后确定装饰器是否能够支持该执行上下文；当支持的行为或限制得到明确确定，并由适当的测试或文档覆盖时，即视为完成。

描述

Hi everyone, I get the Runtime Error when running the function below in Poetry environment with Python 3.11 and Pycharm IDE. I was able to run it successfully from Virtual Environment (the .venv). Can someone offer help on how to fix it?

import numpy as np
import onnx
import onnxruntime
import pandas as pd
from onnxscript import FLOAT
from onnxscript import opset20 as op

x = np.array([1,2,3,4,5,6,7,8,9,10,11,12,13])
y = np.array(x[len(x) - 3: len(x)], dtype=np.float32)
z = np.array(x[len(x)-8: len(x)-3], dtype=np.float32)

x_coef = np.array([1.1, 1.5, 1.7, 1.9, 1.2, 3.1, 4.5, 5.2, 8.5, 9.0, 11.0]
y_coef = np.array([8.5, 9.0, 11.0])
z_coef = np.array([5,7,9,9,10,11])

t1 = len(x)
t2 = len(y)
t3 = len(z)

const_term = 2.37698
h1 = 1.5689
h2 = 1.799

@script()
def conv(a1: FLOAT, a2: FLOAT, a3: FLOAT, a4: FLOAT, a5: FLOAT) -> FLOAT:
    const = op.Constant(value_float=const_term)
    # Define constants
    coeff1 = op.Constant(value_float=h1)
    coeff2 = op.Constant(value_float=h2)
    s = coeff1 * a1  + coeff2 * a2 - const

    for inx in range(t1):
        if a4 == x[inx]:
            s = s + x_coef[inx]
    for inx2 in range(t2):
        if a5 == y[inx2]:
            s = s + y_coef[inx2]
    for inx3 in range(t3):
        if a6 == z[inx3]:
            s = s + z_coef[inx3]
    
    return op.Exp(s)
