执行快速 API 代码时出现此错误fastapi.exceptions.FastAPIError: Invalid args for response field! Hint: check that <class 'main.SoluteSolvent'> is a valid pydantic field type

class SoluteSolvent():
    solvent: Text
    solute: Text

response = {}
@app.get('/predict')
def predict(sol:SoluteSolvent):
    data = sol.dict()
    solute = data['solute']
    solvent = data['solvent']
    results = predictions(solute, solvent)
    print(results)
    response["predictions"] = results[0].item()
    response["interaction_map"] = (results[1].detach().numpy()).tolist()
    return {'result':response}

我实际上试图在快速 API 中复制我为 Flask 中的预测编写的代码。

response = {}
@app.route('/predict', methods=["POST", "GET"])
def predict():
    if request.method=='POST':
        solute = request.form["solute"]
        solvent = request.form["solvent"]

    else:
        solute = request.args.get("solute")
        solvent …

我有一个张量列表，我想将其转换为浮点，我该怎么做。我尝试过使用.item但它不起作用。我正进入（状态ValueError: only one element tensors can be converted to Python scalars。

tensor([[12.1834,  4.9616,  7.7913],
        [ 8.9394,  8.5784,  9.3691],
        [ 9.4475,  8.9766,  9.8418],
        [11.8210,  6.0852,  8.2168],
        [ 8.2885,  6.2607,  9.8877]], grad_fn=<CloneBackward0>)

我正在使用 Flask 进行推理，得到这个结果。他们有什么方法可以将此张量转换为浮点数，因为我想使用此结果在反应应用程序中显示

{
result: {
predictions: "tensor([[-3.4333]], grad_fn=<AddmmBackward>)"
}
}
