I can do something like np.all([np.array_equal(a[0], a[i]) for i in xrange(1,len(a))]) This seems to mix python lists with numpy arrays which is ugly and presumably also slow. Is there a nicer/neater way? A: <code> import numpy as np a = np.repeat(np.arange(1, 6).reshape(1, -1), 3, axis = 0) </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.
