OutOfRangeError (see above for traceback): Read less bytes than requested

[tongpinmo]

when i run the python -m src.flownet2.test --input_a data/samples/0img0.ppm --input_b data/samples/0img1.ppm --out flow_generate the problem is :
OutOfRangeError (see above for traceback): Read less bytes than requested [[Node: save/RestoreV2_130 = RestoreV2[dtypes=[DT_FLOAT], _device="/job:localhost/replica:0/task:0/cpu:0"](_arg_save/Const_0_0, save/RestoreV2_130/tensor_names, save/RestoreV2_130/shape_and_slices)]] [[Node: save/RestoreV2_176/_37 = _Recvclient_terminated=false, recv_device="/job:localhost/replica:0/task:0/gpu:0", send_device="/job:localhost/replica:0/task:0/cpu:0", send_device_incarnation=1, tensor_name="edge_434_save/RestoreV2_176", tensor_type=DT_FLOAT, _device="/job:localhost/replica:0/task:0/gpu:0"]]

i don't know how to solve it? on mint18,cuda8.0,python2.7,with gpu
