Question

请尽快帮我...

这是代码：

list_of_categories = categories +['Others']

print("Classification Report: \n Target: %s \n Labels: %s \n Classifier: %s:\n%s\n"
      % (target,list_of_categories,classifier, metrics.classification_report(y_test, y_pred)))

df_report = pd.DataFrame(data=metrics.confusion_matrix(y_test, y_pred),columns = list_of_categories)
df_report.index = [list_of_categories]
df_report

然后我有这个错误：

/usr/local/lib/python3.7/dist-packages/pandas/core/internals/managers.py in create_block_manager_from_blocks(blocks, axes)
   1679         blocks = [getattr(b, "values", b) for b in blocks]
   1680         tot_items = sum(b.shape[0] for b in blocks)
-> 1681         raise construction_error(tot_items, blocks[0].shape[1:], axes, e)

ValueError: Shape of passed values is (3, 3), indices imply (3, 7)

我不明白...请帮帮我！！！

ValueError: Shape of passed values is (3, 3), indices imply (3, 7)

错误是指调用不存在的行的错误数据帧大小调用。
