The name also does not conflict with any names in NumPy or SciPy. Shuffle means changing arrangement of elements in-place. In this case I think permute, as proposed, would do exactly what a user expects: return the specified permutation of the array. The NumPy Random module provides two methods for this: shuffle() and permutation(). If x is a multi-dimensional array, it is only shuffled along its first index. Does this name conflict with any existing functions? permutation(x) Randomly permute a sequence, or return a permuted range.Would a user expect a function with this name to do what it does?.

When considering new names I think natural questions are: It plans to implement swapaxes as an alternative transposition mechanism, so swapaxes and permute would work on both PyTorch tensors and NumPy-like arrays (and make PyTorch tensors more NumPy-like). Syntax : (x) Return : Return the reshuffled numpy array. PyTorch uses transpose for transpositions and permute for permutations. With the help of () method, we can get the random positioning of different integer values in the numpy array or we can say that all the values in an array will be shuffled randomly. You can also use np.random.permutation to generate random permutation of row indices and then index into the rows of X using np.take with axis0.Also, np.take facilitates overwriting to the input array X itself with out option, which would save us memory.

It would be helpful to provide library writers a mechanism to permute both NumPy-like arrays and PyTorch tensors.

It is the correct mathematical name for the operation.

This issue proposes a new function, permute, which is equivalent to transpose except it requires the permutation be specified. If x is an array, make a copy and shuffle the elements randomly. If x is an integer, randomly permute np.arange (x).

sample method of your data frame to sample all rows without replacement: df.sample (frac1) The frac keyword argument specifies the fraction of rows to return in the random sample, so frac1 means to return all rows (in random order). Randomly permute a sequence, or return a permuted range. If x is an integer, randomly permute np.arange (x). 1485 The idiomatic way to do this with Pandas is to use the. A 'transposition,' however, is typically a swap of two elements, like what swapaxes does. Randomly permute a sequence, or return a permuted range. Today in NumPy there's transpose, which 'reverses or permutes' an array's axes.
