Question

我试图在我的数据集上微调VGG16，但是在打开VGG16权重的h5py文件时遇到了麻烦。我不明白这个错误意味着什么：

OSError: Unable to open file (Truncated file: eof = 221184, sblock->base_addr = 0, stored_eoa = 58889256)

有谁知道如何修复它？感谢

Answer 1

有可能下载文件失败。

使用以下文件替换无法打开的文件可能会解决该问题。 https://github.com/fchollet/deep-learning-models/releases

我的情况，该文件位于以下路径中。 C：\ Users \用户MYNAME \ .keras \模型\ vgg16_weights_tf_dim_ordering_tf_kernels.h5

我替换了它并解决了它。

Answer 2

因为上次文件下载失败。但是错误的文件仍保留在文件路径中。因此您必须找到错误的文件。也许您可以使用“查找/ -name'vgg16_weights_tf_dim_ordering_tf_kernels_notop.h5'”在Unix系统中查找路径。然后删除它尝试阿吉安！祝你好运！

Answer 3

可能是文件下载失败或文件损坏。

我在 /tmp/.keras/models/vggface/ 中发现了那些损坏的文件。

我的系统是 Ubuntu 20.04。

我试图在我的数据集上微调VGG16，但遇到了关于加载VGG16权重的OSError
