使用cifar10求解器培训CNN

我正在用我自己的数据，使用cifar10网络层来培训CNN。但是，当我运行这个命令：使用cifar10求解器培训CNN

[email protected]:~/Desktop/caffe/caffe$ /home/roishik/Desktop/caffe/caffe/build/tools/caffe train --solver /home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_solver.prototxt 2>&1 | tee /home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_train_test.prototxt

我收到此错误信息：

我找遍了谷歌并没有找到答案。这行是什么意思？：

Error parsing text-format caffe.NetParameter: 1:7: Message type "caffe.NetParameter" has no field named "I0726".

真的很感谢您的帮忙！

您的train_val.prototxt或solver.prototxt是否包含字符串“I0726”？ –

请发布'/ home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_train_test.prototxt''的头几行，以便我们看到caffe抱怨的语法错误。 – Shai

哦，tnx注意到我:) – roishik

这是因为你做错了。

您正在使用的文件：

Solver: /home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_solver.prototxt 
Net: /home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_train_test.prototxt 
Log output: /home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_train_test.prototxt

应当指出的是，无论是网络文件和日志文件是相同的，这意味着你与日志数据代替净文件。因此，在caffe求解器读取Net文件时，数据被log取代，从而导致错误。

这应该解决您的问题：

[email protected]:~/Desktop/caffe/caffe$ /home/roishik/Desktop/caffe/caffe/build/tools/caffe train --solver /home/roishik/Desktop/Thesis/Code/cafe_cnn/first/caffe_models/cifar_10_fast/cifar10_quick_solver.prototxt 2>&1 | tee ./log.txt

但要确保你已经取代了覆盖Net文件与正确的文件。

哦，谢谢！你是对的！我忘了写.log而不是.prototxt – roishik
