Tensorflow /移动网络培训/ ValueError：不支持的input_reader_config

Question

I'm trying to traing Mobilenet to recognize custom objects.

I'm following this guide: https://towardsdatascience.com/how-to-train-your-own-object-detector-with-tensorflows-object-detector-api-bec72ecfe1d9

and using a checkpoint and pipeline.config from here: ssdlite_mobilenet_v2_coco

The Problem

When I start traing with the following command:

python object_detection/model_main.py \
--pipeline_config_path=C:\t\models\pipeline.config \
--model_dir=C:\t\models\ \
--num_train_steps=50000 \
--alsologtostderr

I get the following:

C:\tensorflow\models-master\research>path=C:\t\models\pipeline.config \     --model_dir=C:\t\models\ \     --num_train_steps=50000 \     --alsologtostderr

ValueError: Unsupported input_reader_config.

A comment in "dataset_builder.py" says:

Raises: ValueError: On invalid input reader proto. ValueError: If no input paths are specified.

Question:

Is it a problem with pipeline.config file?

Does it mean that "dataset_builder.py" can't read it?

OR

Shall I pass some additional input path as it stated in the comment?

Answer 1

If I remember correctly, cause of the problem was I didn't prepare test data. There was a training data only. So I prepared a list of test images with related XML files and generated test TFrecord.

Then the error has gone.

PS I had a lot of other errors later but it's another story :)
