安装scikitlearn的车轮时出现弃用警告

Question

我是Python新手。有人能告诉我该怎么解决这个错误吗。在

C:\Users\admin\Desktop\Hiwi\Python Programs>py TSP.py
C:\Users\admin\AppData\Local\Programs\Python\Python38-32\lib\site-packages\sklearn\externals\six.py:28: DeprecationWarning: The module is deprecated in version 0.21 and will be removed in version 0.23 since we've dropped support for Python 2.7. Please rely on the official version of six (https://pypi.org/project/six/).
  warnings.warn("The module is deprecated in version 0.21 and will be removed "
Traceback (most recent call last):
  File "TSP.py", line 4, in <module>
    fitness_coords = mlrose.TravellingSales(coords=coords_lists)
NameError: name 'coords_lists' is not defined

提前谢谢你。在

Answer 1

首先，它不是一个错误，只是一个warning。接下来，从py TSP.py看来，您实际上是在尝试运行一个python脚本。在

在第四行fitness_coords = mlrose.TravellingSales(coords=coords_lists)中，coords_lists似乎之前没有定义。在

你想运行this？？？在

然后您需要在TSP.py文件中包含如下内容：

# Create list of city coordinates
coords_list = [(1, 1), (4, 2), (5, 2), (6, 4), (4, 4), (3, 6), (1, 5), (2, 3)]

# Initialize fitness function object using coords_list
fitness_coords = mlrose.TravellingSales(coords = coords_list)

对于警告，请在.py文件中使用以下命令：
