关于TypeError: unhashable type: ‘list‘ 错误的解决

在用python写代码遇到了这个错误：

 File "/home/dwt/MyCode/pycharm_projects/YOLOX/yolox/models/darknet_search.py", line 196, in 
    self.dark3 = nn.Sequential(*[PRIMITIVES[block_names[i]](*input_parameter(i))

TypeError: unhashable type: 'list'

报错原因：是因为代码中input_parameter是一个储存若干元组的列表，内容如下：

input_parameter = [ 
                (32, 64, -999, 2), (64, 64, -999, 1), (64, 64, -999, 1), (64, 64, -999, 1),
                (64, 128, -999, 2), (128, 128, -999, 1), (128, 128, -999, 1), (128, 128, -999, 1),
                (128, 256, -999, 2), (256, 256, -999, 1), (256, 256, -999, 1), (256, 256, -999, 1),
                (256, 512, -999, 2), (256, 512, -999, 1), (256, 512, -999, 1), (256, 512, -999, 1),
]

而错误之处是“input_parameter(i)”，对列表中元素索引时，应该用中括号标记索引值，而不是小括号。将“input_parameter(i)”改为“input_parameter[i]”即可。
