Cannot feed value of shape for Tensor when predicting model with image

I get this error when trying to perform prediction with a new image on trained model:

Traceback (most recent call last):

ValueError: Cannot feed value of shape (1,) for Tensor 'image_path/image_path:0', which has shape '(?, 100, 100, 3)'

The model definition I use:

input_features:
    -
        name: image_path
        type: image
        encoder: stacked_cnn
        in_memory: false
        height: 100
        width: 100

output_features:
    -
        name: tags
        type: set`

Example of testing csv-file:

image_path,tags
testdata/cat.101.jpg

I’ve tried output features with category and set types but eventually get that error.

@w4nderlust Ok, thanks, here the link to my dataset sample and commands I use ludwig-prediction-example.zip

Got it, it may be the case that I’m not correctly applying the preprocessing to image features in prediction. Will look into it. @ydudin3 can you also try to check this out?
