尝试打开 h5 文件时出现 filenotfound 错误

Question

我有一个包含“catvnoncat”数据集的 h5 文件。当我尝试运行以下代码时，出现错误，我将其包含在底部。我尝试从三个不同的来源获取数据集以排除文件损坏的可能性。

我想知道是什么导致了这个问题？

# My Code
import h5py
train_dataset = h5py.File('train_catvnoncat.h5', "r")

# The Error

Answer 1

您的代码正在当前目录中查找，该目录不是文件所在的目录。

根据错误消息，您似乎在 windows。文件 'train_catvnoncat.h5' 是否在您的“下载”文件夹中？在您的系统上找到该文件并复制完整路径。然后你可以更新这个：

train_dataset = h5py.File('train_catvnoncat.h5', "r")

到包含完整路径的内容。类似这样：

train_dataset = h5py.File('C:/Users/Moshen/Downloads/train_catvnoncat.h5', "r")

注意斜线并确保将文件路径更新为实际值。
