TypeError: 'numpy.float64' object cannot be interpreted as an integer

原因：cocoeval.py文件中调用的了np.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None)函数。新版本的numpy要求num为整数。
修改：修改Lib\site-packages\pycocotools文件下cocoeval.py文件，修改507等行如下:

self.iouThrs = np.linspace(.5, 0.95, int(np.round((0.95 - .5) / .05)) + 1, endpoint=True)
self.recThrs = np.linspace(.0, 1.00, int(np.round((1.00 - .0) / .01)) + 1, endpoint=True)
