Package: arrgh
arrghA small python utility to pretty-print a table summarizing arrays/tensors/scalars from numpy, pytorch, etc.Why the name?"arr" is short for "array", and "arrgh" is the sound you make while debugging your array shapes.ExampleCallingarrgh(my_arr1, my_arr2, ...)prints a table like:name | dtype         | shape         | type          | device | min         | max         | mean

Call it like:arrgh(my_arr, some_other_arr, maybe_a_scalar).The function accepts a variable number of arguments. Arrays can also be passed as named optional arguments.Inputs can be:Numpy tensor arraysPytorch tensor arraysJax tensor arraysPython ints / floatsNoneIt may also work with other array-like types, but they have not been tested.Input values which are not arrays or numeric types (strings, objects, etc) will be printed as blank rows in the table.When arrays are passed as variable arguments, the printed name of the array in the table is inferred from the variable name in the outer scope, when possible. When arrays are passed as named keyword arguments, the key name is used.Pass an integer for thearrgh_float_widthoption to specify the precision to which floating point types are printed.Author: Nicholas Sharp (nmwsharp.com)
