D:\Anaconda3\lib\site-packages\h5py__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type. from ._conv import register_converters as _register_converters
solution
According to this link将numpy回退版本
For anyone coming here with this problem, it is a known h5py issue, introduced with numpy 1.14. As stated by the devs:
You can ignore the warning, it's not going to cause any issues at the moment, but you should upgrade to the next release of h5py when it becomes available.
... so it's harmless. The fix has just been merged to master. But until the update is released, the workaround is to downgrade numpy to a previous version:
pip install numpy==1.13.0
