ValueError: Unable to create group (name already exists)

問題描述：

在tensorflow2.0.0下保存模型出現的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)

ValueError: Unable to create group (name already exists)

解決方法

參考此連接 ，修改模型後綴爲.tf/後者升級tf版本爲2.0.0以上。採用修改模型後綴爲.tf暫時解決。
