TypeError: test() missing 1 required positional argument

Question

I want to predict a score for each sentence in a text. I have written this test method:

def test(sent):
    # Predict for a given sentence
    if sent != "":
        input, seq_lengths, target = make_variables([sent], [])
        output = classifier(input, seq_lengths)
        pred = output.data.max(1, keepdim=True)[1]
        score = pred.cpu().numpy()[0][0]
        print("The sentence is:",sent, "The score is:", score)
        return


    print("evaluating trained model ...")
    total_mse=0

    for sents, scores in test_loader:
        input, seq_lengths, target = make_variables(sents, scores)
        output = classifier(input, seq_lengths)
        pred = output.data.max(1, keepdim=True)[1]
        error=mean_squared_error(pred,target.data.view_as(pred.float()))
        total_mse +=error
    print(" **********  Total MSE is   **********",total_mse)
    return

In a part of main method, I have:

# Testing
test("")
# Testing for a given sample _a sentence_
test("For instance, wolves prey on moose, which are too big for coyotes.")

But I received this error:

I think that test() has its argument 'sent'. How can I correct this error?

使用nose或单元测试运行测试并unittest ，如果您是新手，我认为您可以更轻松地开始使用pytest类的pytest
