I can take the first element of this array to manually convert it to a 1D array: b = np.reshape(a, (1,np.product(a.shape)))[0] but this requires me to know how many dimensions the original …

May 11, 2011 · In case of 1D numpy array (rank-1 array) the shape and strides are 1-element tuples and cannot be swapped, and the transpose of such an 1D array returns it unchanged. …

Sep 25, 2012 · I want to convert a 1-dimensional array into a 2-dimensional array by specifying the number of columns in the 2D array. Something that would work like this: > import numpy …

Aug 2, 2018 · Hence, it is not the same a 1D array of 1D arrays, that is, an array with dimensions (A,) filled of objects of type array with shapes (B,) than an array with shape (A,B). For …

I guess there is a trick to make it work but I don't know how. I saw that KMeans.fit() accepts "X : array-like or sparse matrix, shape=(n_samples, n_features)", but it wants the n_samples to be …

There are several possibilities for concatenating 1D arrays, e.g., import numpy as np np.r_[a, a] np.stack([a, a]).reshape(-1) np.hstack([a, a]) np.concatenate([a, a])

Dec 10, 2012 · Hi, Thanks for the answer. This is the way I tried the first time, but may be I was not able to explain my question properly. The plot it draws is a continuous lines made by …

Late response and just for the record. You can partition a 1D array using Ckmeans.1d.dp. This method guarantees optimality and it is O(n^2), where n is the num of observations. The …

Oct 3, 2009 · @AndersonGreen As I said there's no such thing as a variable declaration in Python. You would create a multidimensional list by taking an empty list and putting other lists …

May 8, 2014 · If you guys know other way to visualize 1D arrays into a single line I would very much appreciate, especially if it involves colors representing density of values. I'm using …
