Unfortunately, I'm running into stability issues with eigsh() . Here's my code: import numpy as np import scipy.sparse import scipy.sparse.linalg as SLA import sklearn.utils.graph as graph W = self._sparse_rbf_kernel(self.X_, self.datashape) D = scipy.sparse.csc_matrix(np.diag(np.array(W.sum(axis = 0))[0])) L = graph.graph_laplacian(W) # D - W vals, vects = SLA.eigsh(L, k = self

I need this app to have a small apk size (not more than 10mb ) and work on 3G network. Based on my research if I remove x86 JS binary files from React Native the apk size could be as small as 4mb. I suppose the 4mb does not include the JS files and images so client needs to download that first time when he/she opens the app, is that correct? Would it in general be a good idea for me to use React Native

After many years and many approaches I tend to agree in general with the staterment: "For any protected software used by more than a few hundred people, you can find a cracked version. So far, every protection scheme can be tampered with." Does your employer enforce the use of anti-piracy software? Further, every time I post about this subject, some one will remind me; "First of all, no matter what kind of protection you'll employ,a truly dedicated cracker will, eventually, get through

I tried to insert some text in an Excel field that was 262 characters long and got this error: The
