RuntimeError:当我附加hdf5文件时，无法创建链接(名称已经存在)? [英] RuntimeError: Unable to create link (name already exists) when I append hdf5 file?

问题描述

我正在尝试将hdf5数据集附加到先前的hdf5数据集
发生以下错误

I am trying to append the hdf5 dataset to the previous hdf5 dataset
following error occured

h5o.link(obj.id，self.id，name，lcpl = lcpl，lapl = self._lapl)文件 "h5py/_objects.pyx"，在h5py._objects.with_phil.wrapper中的第54行，

        for idx, (img, target) in enumerate(dataloader):

                print('Save_saliency_maps::',idx)

推荐答案

1. 转到: Miniconda3 \ Lib \ site-packages或任何安装h5py的地方.

1. Go to: Miniconda3\Lib\site-packages or wherever h5py is installed.

删除h5py文件夹

删除h5py-2.10.0.dist-info文件夹(如果您使用其他版本，则可能会有所不同.)

Delete h5py-2.10.0.dist-info Folder (This might be different if you have a different 4. version).

再次安装h5py.

经过长时间的搜索，它对我有用. 最后，我尝试手动将其删除并重新安装. 它工作了！！！！！！

It worked for me after a long search. Finally, I tried to delete it manually and reinstall it. IT WORKED!!!!!

通过使用cmd，pip和anaconda卸载它们 某些文件可能会卡住，甚至在安装其他版本后也会导致错误.

By uninstalling them using cmd, pip, anaconda Some files might stuck and will cause errors even after installing a different version.
