SyntaxError in the file "src/handlers/data_generator.py"

[chenjw851009]

hi , when I run the src code "train.py" ,one error report. this is:

File "/work/imageQuality/image-quality-assessment-master/src/handlers/data_generator.py", line 39
X = np.empty((len(batch_samples), *self.img_crop_dims, 3))

the parameter numbers is 3 or 2 in the function np.empty ?

I just learn python, so may be this is a very simple question for you.
sweet smile! thanks

[chenjw851009]

the parameter "img_crop_dims=(224,224)",what do the parameter"*self.img_crop_dims"mean?

I install keras of version 2.1.2, when I train my own model, some error report like this:

=================================================================
Total params: 3,239,114
Trainable params: 10,250
Non-trainable params: 3,228,864

when I run train.py without docker, it ask two other files, "samples.json" and "config.json" ,I copy them from you have provided, but one para in the "config.json" is: "docker_image": "nima-cpu",

{
"train_env": "TID2013",
"s3_bucket": "ds-hotel-image-assessment",
"docker_image": "nima-cpu",
"base_model_name": "MobileNet",
"existing_weights": null,

"batch_size": 64,

"decay_all": 0,
"dropout_rate": 0.75,
"multiprocessing_data_load": true,
"num_workers_data_load": 8,
"img_format": "bmp"
}
there are some para about docker, but I use python without docker, so what I should modify the config.json?? can you tell me how to do?
thanks very much!!!

I have fixed this issue, but it seems that there is a bug in your source file code which named "data_generator.py",in the line 39.
besides, I run the train.py successfully in the version tensorflow:1.12.0 ,Keras:2.1.6 and python:2.7.12.
however, thanks very much.

Hi, glad that you got the train.py script running. It seems all your issues are package version related, which is why I recommend to use the provided Docker images for training and predicting.

Line 39 in data_generator.py has no bug I believe, it works fine with the numpy version in the Docker image.
