python - 如何处理无法打开的 HDF5 文件

Question

我正在使用 Python h5py 库，我不是 C/C++ 程序员。

我有一个文件无法读取，因为创建数据集的长写入操作被中断。

如果可能的话，我希望能够打开文件并删除损坏的数据集，以便我可以重新加载它而不会丢失所有其他数据。

我尝试使用给定的错误消息在以下 HDF5 实用程序中打开该文件。

• h5转储： h5dump error: unable to open file "test.h5"

• 高清视图：Error opening file test.h5

• HDF罗盘：

任何有关如何进行的线索将不胜感激。提前致谢。
