python - 类型错误 : 'dict_values' object is not subscriptable

Question

best_params_train = dict(optimizer=optimizers[0], learning_rate=learning_rates[0],
                         cnn_train_type=cnn_train_types[0], 
                         cnn_arch=cnns_arch.values()[0],
                         dropout=dropouts[0])

它在 cnn_arch=cnns_arch.values()[0] 处给出错误，因为 TypeError: 'dict_values' object is not subscriptable。
我尝试转换为列表但没有用。
如何将上面的 dict(....) 转换成列表

exp_params_train = dict(optimizer=optimizers[1:], learning_rate=learning_rates[1:],
                        cnn_train_type=cnn_train_types[1:], dropout=dropouts[1:],
                        cnn_arch=cnns_arch.values())

Answer 1

恰恰相反，如果您转换 dict_values 它将起作用反对一个列表:

cnn_arch=list(cnns_arch.values())[0]
