specify the numpy version

[juexZZ]

Hi Zhongdao, can you specify the Numpy version compatible with all the other dependencies? It is not specified in the requirements.
I am trying to run your code for my project but getting dependency errors with cython_bbox and pycocotools. They seem to be related to specific Numpy versions.
Thanks!

To be more specific: for numy versions>=1.20 I got errors for cython_bbox(0.1.3):

File "src/cython_bbox.pyx", line 1, in init cython_bbox
ImportError: numpy.core.multiarray failed to import (auto-generated because you didn't call 'numpy.import_array()' after cimporting numpy; use 'numpy._import_array' to disable if you are certain you don't need it).

And for numpy==1.19.5 I got errors with pycocotools:

import pycocotools._mask as _mask
File "pycocotools/_mask.pyx", line 1, in init pycocotools._mask
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject
