ValueError：找到样本数不一致的输入变量：[75,1]

Question

有人可以告诉我这是什么样的错误以及如何解决这个问题（如图所示）

，这是错误消息

Traceback (most recent call last):
  File "ep5pipeline.py", line 57, in <module>
    print (accuracy_score(y_test,predictions, normalize = False))
  File "//anaconda/lib/python3.6/site-packages/sklearn/metrics/classification.py", line 172, in accuracy_score
    y_type, y_true, y_pred = _check_targets(y_true, y_pred)

    " samples: %r" % [int(l) for l in lengths])
ValueError: Found input variables with inconsistent numbers of samples: [75, 1]

Answer 1

在函数predict（）中，return predictions应该出现在＆＃34; for＆＃34;迭代。

此外，像Neil说的那样，最好发布源代码。
