For social network analysis I'd like to make a simple undirected graph. So I need to convert the matrix to binary matrix. My question: is there a fast, convenient way to reduce the decimal matrix to a binary matrix. Such that: 26, 3, 0 3, 195, 1 0, 1, 17 Becomes: 1, 1, 0 1, 1, 1 0, 1, 1 A: <code> import scipy import numpy as np a = np.array([[26, 3, 0], [3, 195, 1], [0, 1, 17]]) </code> a = ... # 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.
