Unexpected behaviour of Histogram when using nbins

1

Hello, I would like to report on the following issue. Suppose that you want to produce an histogram with a data set defined between, say, xmin and xmax, with an...

I am trying to create a data set of the type: t1 t2 t3... 1 2 3... 5 6 7... ... ... Where t1 t2 t3 are labels that give...

Is there a practical example of use of imfilter in GPUs?

Hello! I am interested in using Julia/imfilter for a deconvolution problem in particle physics. In short, our experiment (http://next.ific.uv.es/next/) takes "electronic movies" of electrons propagating in dense xenon gas. We...

In dt5.ipynb one finds the code: ``` import pytomography from pytomography.metadata import ObjectMeta, ImageMeta, PSFMeta from pytomography.transforms import SPECTAttenuationTransform, SPECTPSFTransform from pytomography.projections import SystemMatrix ``` All import fail, apparently they...

In notebook dt1.ipynb, the line ``` angles = np.arange(0,360.,3) ``` should be replaced by: ``` angles = torch.arange(0,360.,3) ``` Also, I think there is a typo here: ``` plt.pcolormesh(obj[0].sum(axis=2).T, cmap='Greys_r')...

To make the code compatible with MacOS I commented the line below: #device = torch.device("cuda" if torch.cuda.is_available() else "cpu") And used instead: ``` device = ( "cuda" if torch.cuda.is_available() else...

In notebook: $f$ refers to an object, and $f_j$ refers to the value of the object at voxel $j$ * $g$ refers to a set of projections, and $g_i$ refers...
