To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations WARNING:torch.distributed.elastic.multiprocessing.api:Sending process 29887 closing signal SIGTERM ERROR:torch.distributed.elastic.multiprocessing.api:failed (exitcode: 1) local_rank: 0 (pid: 29886) of binary: /home/wangbei/anaconda3/envs/Object_mmdetection/bin/python

这个错误看起来像是在使用numpy时出现了问题。根据错误信息，似乎是在`pycocotools/cocoeval.py`文件中的`np.float`出现了问题。这是因为在NumPy 1.20中，`np.float`被弃用了。为了解决这个问题，你需要将代码中的`np.float`替换为`float`或`np.float64`。

你可以在`pycocotools/cocoeval.py`文件中找到`tp_sum = np.cumsum(tps, axis=1).astype(dtype=np.float)`这一行代码，将其中的`np.float`替换为`float`或`np.float64`。如果你不确定应该使用哪个，请根据NumPy版本查看官方文档或参考错误信息中提供的链接。

在修改代码后，重新运行程序，应该就可以解决这个问题了。
