KeyError: "The name 'inputs:0' refers to a Tensor which does not exist. when compile mobilenet v1

Hello, guys. Now I retrained mobilenet v1 model to fine-tune it's output layer to 8 classes. It works well but when I tried to compile it into NCS graph some error happens and please help me.

 

For this model, I have ckpt files like model.ckpt.meta or model.ckpt.index and so on.

 

And in terminal, I use the command:

 

mvNCCompile ./model.ckpt-70310.meta -s 12 -in=inputs -on=MobilenetV1/Logits/Predictions -is 224 224 -o MobilenetV1.graph

 

and it outputs:

 

vNCCompile v02.00, Copyright @ Intel Corporation 2017

 

_* Info: No Weights provided. inferred path: ./model.ckpt-70310.data-00000-of-00001_*

I use slim in tensorflow model to fine-tune mobilenet v1.

@Meow10

 

Just, there is no placeholder named "inputs".

 

Please post the Python code used for training.

@PINTO I modified the 'train_image_classifier.py' in tensorflow slim and used the script to train the mobilenet V1. The script is as follows:

 

set -e

 

PRETRAINED_CHECKPOINT_DIR=./checkpoints

 

TRAIN_DIR=./models/mobilenet_v1_224

 

DATASET_DIR=./data

 

python train_image_classifier.py \

 

--train_dir=${TRAIN_DIR} \

 

--dataset_name=flowers \

 

--dataset_split_name=train \

 

--dataset_dir=${DATASET_DIR} \

 

--model_name=mobilenet_v1 \

 

--checkpoint_path=${PRETRAINED_CHECKPOINT_DIR} \

 

--checkpoint_exclude_scopes=MobilenetV1/Logits \

 

# --trainable_scopes=mobilenet_v1/Logits \

 

--max_number_of_steps=100 \

 

--batch_size=32 \

 

--learning_rate=0.01 \

 

--save_interval_secs=60 \

 

--save_summaries_secs=60 \

 

--log_every_n_steps=100 \

 

--optimizer=rmsprop \

 

--weight_decay=0.00004

 

and the code for mobile V1 in slim is as follows:
