The medical image data preprocessing function splits the transformed NumPy arrays into four distinct "groups," which are then stored in four separate datasets (hdf5). This is evident in the way the function operates (LoadIPV()). My concern is to accumulate the next 100 NumPy arrays in a s...
Below is an example where I am plotting two random arrays. plt.rc('text', usetex=True) plt.rc('font', family='serif') y1 = np.random.random(10) y2 = np.random.random(10) fig, ax = plt.subplots(ncols=2, figsize=(8, 3)) # equivalent to your figure ax[0].plot(y1, 'o-...
Learning blocks operate on data that has already been processed by aninput blockand aprocessing block. This processed data is available to your learning block in a single directory, in the NumPy format, and already split into training (train) and validation (test) datasets. By default the trai...
Numpy.pad() in Python, Reshape arbitrary length vector into square matrix with padding in numpy, Zero Padding a 3d Numpy array
The reason I mention it's jarring is that the numpy interface generally gives the sense that is is underpinned by C. For example there are structured arrays, you can access pointers to the raw data structures, there are tables like this: https://numpy.org/devdocs/user/basics.types.html ...
This limitation on xtensor::reshape is because it operates in place, like in NumPy. I think we don't want to mix "copy" and "in-place" behaviors in the same function (at least implicitly), so an additional free function (although the name copy_and_reshape might not be ideal) looks ...

A voxel represents a value on a regular grid in three-dimensional space (like 3D pixels). The voxel coordinate system describes how an image was acquired with respect to the anatomy. Medical scanners create regular, rectangular arrays of points and cells which start at the upper left corner. ...
