Question

我正在训练一个简单的网络。由于无法运行caffe，我决定仅对20张图像进行测试。但我无法通过以下错误消息。我按照其他帖子的建议重建了caffe，但没有解决问题。

我感觉它是由我的求解器文件引起的。这是我的解决者。

net: "/X/train.prototxt"
test_iter: 5
test_interval: 5
base_lr: 0.01
momentum: 0.9
weight_decay: 0.0005
lr_policy: "step"
stepsize: 5
gamma: 0.1
power: 0.75
display: 5
max_iter: 20
snapshot: 10
snapshot_prefix: "/X/A"
solver_mode: GPU

你在我的求解器上看到任何问题吗？

干杯，

Answer 1

您的型号是否大于2gb？如果是这样，这个错误可能是由于protobuf格式的限制。尝试添加

snapshot_format: HDF5

在你的solver.prototxt末尾改为以hdf5格式保存。
