我运行我的代码,它在第79行中引发错误:
numpy.core._exceptions.UFuncTypeError: ufunc 'add' did not contain a loop with signature matching types (dtype('<U21'), dtype('<U21')) -> dtype('<U21').
每个人都知道如何解决,请帮助我。非常感谢。 我的代码:
68 multi_df = pd.read_csv(FLAGS.VoTT_csv)
69 labels = multi_df["label"].unique()
70 labeldict = dict(zip(labels, range(len(labels))))
71 multi_df.drop_duplicates(subset=None, keep="first", inplace=True)
72 train_path = FLAGS.VoTT_Folder
73 convert_vott_csv_to_yolo(
74 multi_df, labeldict, path=train_path, target_name=FLAGS.YOLO_filename
75 )
76 file = open(classes_filename, "w")
77 SortedLabelDict = sorted(labeldict.items(), key=lambda x: x[1])
78 for elem in SortedLabelDict:
79 file.write(elem[0] + "\n")
80 file.close()
答案 0 :(得分:1)
可能的情况是,第79行中的elem[0]
不是字符串,而是numpy中的数字类型。
尝试将第78和79行更改为此:
for elem in SortedLabelDict:
file.write(str(elem[0]) + "\n")
