On training times, many people will understand the misunderstanding, that training is the number, the more the better. For training practice samples, train more, the higher degree of fitting, but the validation sample error does not necessarily become smaller and smaller. Because when a network ...

ValueError: With n_samples=0, test_size=0.3 and train_size=None, the resulting train set will be empty. Adjust any of the aforementioned parameters. 解决思路 值错误:当n_samples=0, test_size=0.3和train_size=None时,得到的train 集将为空 ...
该函数用于将数据集分成训练集和测试集。train_size和test_size参数用于指定训练集和测试集的相对大小。当我们将train_size设置为None时,它默认为1-test_size。而当我们在n_samples=0时,实际上是没有任何数据可以分配到训练集中的。 为了解决这个问题,我们需要调整上述参数。如果n_samples=0,我们需要增加数据集的...
