问题形容：
在tensorflow2.0.0下保留模型呈现的bug,
File "/usr/local/lib/python3.6/dist-packages/tensorflow_core/python/keras/saving/hdf5_format.py", line 103, in save_model_to_hdf5 save_weights_to_hdf5_group(model_weights_group, model_layers) File "/usr/local/lib/python3.6/dist-packages/tensorflow_core/python/keras/saving/hdf5_format.py", line 619, in save_weights_to_hdf5_group g = f.create_group(layer.name) File "/usr/local/lib/python3.6/dist-packages/h5py/_hl/group.py", line 68, in create_group gid = h5g.create(self.id, name, lcpl=lcpl, gcpl=gcpl) File "h5py/_objects.pyx", line 54, in h5py._objects.with_phil.wrapper File "h5py/_objects.pyx", line 55, in h5py._objects.with_phil.wrapper File "h5py/h5g.pyx", line 161, in h5py.h5g.createValueError: Unable to create group (name already exists)解决办法
参考此链接 ，批改模型后缀为.tf/后者降级tf版本为2.0.0以上。采纳批改模型后缀为.tf临时解决。
