问题
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) File "h5py/_objects.pyx", line 54, in h5py._objects.with_phil.wrapper
File "h5py/_objects.pyx", line 55, in h5py._objects.with_phil.wrapper File "h5py/h5o.pyx", line 202, in h5py.h5o.link RuntimeError: Unable to create link (name already exists)
sal_maps = np.array([], dtype=np.float32).reshape((0,) + img_size)
probs = np.array([], dtype=np.float32)
preds = np.array([], dtype=np.uint8)
for idx, (img, target) in enumerate(dataloader):
# TODO problem1 idx problem
sal_maps_b, probs_b, preds_b = self.generate_image(img, idx)
sal_maps_b = np.transpose(sal_maps_b, axes=(3,0, 1, 2))
sal_maps = np.vstack([sal_maps,sal_maps_b])
probs = np.append(probs, probs_b)
preds = np.append(preds,preds_b)
#if idx ==2: break
if idx % 100 == 0:
print("idx->{} sal_maps->{}, probs->{} , preds->{}".format(idx,sal_maps.shape,probs.shape,preds.shape))
# TODO indent change
print("result->{}".format(sal_maps.size))
with h5py.File(self.datapath, 'a') as hf:
hf.create_dataset('saliencys', data=sal_maps)
hf.create_dataset('probs', data=probs)
hf.create_dataset('preds', data=preds)
hf.close()
sal_maps = np.array([], dtype=np.float32).reshape((0,) + img_size)
probs = np.array([], dtype=np.float32)
preds = np.array([], dtype=np.uint8)
print('Save_saliency_maps::',idx)
回答1:
Go to: Miniconda3\Lib\site-packages or wherever h5py is installed.
Delete h5py Folder
Delete h5py-2.10.0.dist-info Folder (This might be different if you have a different 4. version).
Install h5py again.
It worked for me after a long search. Finally, I tried to delete it manually and reinstall it. IT WORKED!!!!!
By uninstalling them using cmd, pip, anaconda Some files might stuck and will cause errors even after installing a different version.
