# ds1000 / 971 - taskset: [ds1000](https://harnessreport.com/tasks/ds1000.md) - difficulty: - category: - language: - runnable from the site: no - agent timeout: 1800s ## Results by harness _none yet_ ## Instruction ``` # 971: DS-1000 Task ## Prompt Problem: I have the tensors: ids: shape (70,1) containing indices like [[1],[0],[2],...] x: shape(70,3,2) ids tensor encodes the index of bold marked dimension of x which should be selected. I want to gather the selected slices in a resulting vector: result: shape (70,2) Background: I have some scores (shape = (70,3)) for each of the 3 elements and want only to select the one with the highest score. Therefore, I used the function ids = torch.argmax(scores,1,True) giving me the maximum ids. I already tried to do it with gather function: result = x.gather(1,ids) but that didn't work. A: <code> import numpy as np import pandas as pd import torch ids, x = load_data() </code> result = ... # put solution in this variable BEGIN SOLUTION <code> ## What to do - Edit `solution/solution.py` so the code passes the DS-1000 tests. - Do not access the internet or install new packages; required libraries are preinstalled in the Docker image. - Run tests locally via `bash tests/test.sh`. ## Notes - Keep the variable names/signatures implied by the prompt/code_context. - The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`). ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
