opt_einsum.contract(subscripts, *operands[, …]) |
Evaluates the Einstein summation convention on the operands. |
opt_einsum.contract_path(*operands, **kwargs) |
Evaluates the lowest cost einsum-like contraction order. |
opt_einsum.contract_expression(subscripts, …) |
Generate an reusable expression for a given contraction with specific shapes, which can for example be cached. |
opt_einsum.contract.ContractExpression(…) |
Helper class for storing an explicit contraction_list which can then be repeatedly called solely with the array arguments. |
opt_einsum.paths.optimal(input_sets, …) |
Computes all possible pair contractions, sieves the results based on memory_limit and returns the lowest cost path. |
opt_einsum.paths.greedy(input_sets, …) |
Finds the path by contracting the best pair until the input list is exhausted. |
opt_einsum.parser.get_symbol(i) |
Get the symbol corresponding to int i - runs through the usual 52 letters before resorting to unicode characters, starting at chr(192). |
