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

[idata]

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:

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_224DATASET_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:
