No data for this layer

[guozhizou]

Quiver start normally, model and images are all visiable, but when I clicked the Input Layer (or other layers), got an error:

Any ideas?

E tensorflow/core/client/tensor_c_api.cc:485] input_1:0 is both fed and fetched.

Did you install with pip or clone the git repo? Similar issues were fixed very recently, may just need an update.

I cloned the repo and builded from master yesterday.

Fixed after reinstalled.
