Can it be done using scipy.cluster.hierarchy? I tried to do that but failed. Anyone can give me some advice? prefer answer in a list like [label1, label2, ...]\n\nA:\n\n<code>\nimport numpy as np\nimport pandas as pd\nimport scipy.cluster\ndata_matrix = load_data()\n</code>\ncluster_labels = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n\n## What to do\n- Edit `solution/solution.py` so the code passes the DS-1000 tests.\n- Do not access the internet or install new packages; required libraries are preinstalled in the Docker image.\n- Run tests locally via `bash tests/test.sh`.\n\n## Notes\n- Keep the variable names/signatures implied by the prompt/code_context.\n- The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`).\n", "memory": "", "runnable": false, "difficulty": "", "language": "", "cpus": "", "instruction_truncated": false, "category": "", "compose": false, "has_solution": true, "oracle": null, "docker_image": "ds1000:latest", "taskset": "ds1000", "tags": []}, "runs": []}
