Hi,
the error is about the backend implementation for the radon transform. The default is 'astra_cuda'
, which requires both the astra-toolbox being installed and a cuda-enabled GPU. For testing, you can pass the option impl='skimage'
to get_standard_dataset
. But for real use, this will probably be too slow.If you are using anaconda, the latest development version of astra can be installed with
conda install astra-toolbox -c astra-toolbox/label/dev
Then the backends 'astra_cpu'
and 'astra_cuda'
should become available ('astra_cuda'
only if cuda is available).
As for downloading the data, it should not be related to this issue. The automated download using dival usually works, however users have reported robustness issues, which may occur especially if the network connection to the zenodo.org servers is weak.
Best regards, Johannes
Thank you. Works with the additional option.
Personally it would have helped me if your answer would be part of the README.md
.
Looking forward to play around with the datasets!
Great, thanks for the feedback, will add it to the README!
Hi,
I wanted to use
dival
to get access to your standard datasets (ellipses
andlodopab
).I installed
divial
viapip install dival
.Then I executed the following lines:
And got this error:
Would you recommend to download the data via zenodo instead?
Cheers
