您好,请问用给出的预训练权重微调分类模型, 多个Epoch 后得到的准确率只有 7%,请问是什么原因呢
[11/21 11:46:59 train]: Epoch: [68][99/104] ETA: 0:13:42 total_loss: 3.048 iter_time: 0.0598 data_time: 0.0002 lr: 0.0022951 max_mem: 4538M
[11/21 11:47:01 train]: Epoch: 68 acc@1: 3.1250 acc@5: 16.8269
[11/21 11:47:01 train]: Max accuracy: 7.45%

我的 UCM 数据集是按照 8:2 去分割的

数据集:
freeway23.tif 8
tenniscourt49.tif 20
mediumresidential89.tif 12
river83.tif 16

我也一样,在UCM分类上,我用给的预训练权重训练200个epoch,准确率也是个位数,用作者放出来的微调好的权重,准确率也只有17%
