@sven1977 Hi Sven,  
I think [[RLlib] Problem with TFModelV2 loading after having saved one with `TFPolicy.export_model()` - #2 by morsias](https://discuss.ray.io/t/rllib-problem-with-tfmodelv2-loading-after-having-saved-one-with-tfpolicy-export-model/745/2) is a similar issue.  
Looks like you need to have a reproducible script, please check it out mine.

here’s my test code.

> <https://gist.github.com/kepricon/516800ad7d8ef1b0b23df429c4d49490>

with Ray 1.0.0,  
executed my test code and try to load the model.  
tf.saved\_model.load(‘model\_1\_0\_0’) works well.

with Ray 1.0.1.post1  
executed my test code and try to load the model.  
tf.saved\_model.load(‘model\_1\_0\_1\_post1’) doesn’t work.
