ValueError: You are trying to load a weight file containing 293 layers into a model with 147 layers.

Hi,

So, I was trying to use Pixellib to do some segmentation on a video and wanted to load the xception model that was trained on the Pascal voc dataset. Should've been a straight forward task with 5 lines of code, however, I ran into some issue:

I used the following link to download the model: https://github.com/ayoolaolafenwa/PixelLib/releases/download/1.1/deeplabv3_xception_tf_dim_ordering_tf_kernels.h5

But when I try to load the load, I get this error:

---------------------------------------------------------------------------

ValueError: You are trying to load a weight file containing 293 layers into a model with 147 layers.

Following is the code that I am using:

import pixellib
from pixellib.semantic import semantic_segmentation
segment_video = semantic_segmentation()
segment_video.load_pascalvoc_model("deeplabv3_xception_tf_dim_ordering_tf_kernels.h5")

Kindly look into this issue and let me know how to resolve it.

Thanks,

I fixed using installing Tensorflow==2.6.0 and Keras==2.6.0

!pip3 install tensorflow==2.6.0 !pip3 install keras==2.6.0

!pip3 install tensorflow==2.6.0 !pip3 install keras==2.6.0

Thanks. So, the potential fix is to downgrade the TF from 2.9.1 to 2.6.0 and Keras from 2.9.0 to 2.6.0 because PixelLib is not compatible with the newer versions?

I think so. One more thing!! When you are training there are more error maybe will come. So in that case Try... !pip3 install tensorflow==2.6.0 !pip3 install keras==2.6.0 !pip3 install imgaug !pip3 install pillow==8.2.0 !pip install pixellib==0.5.2 !pip install labelme2coco==0.1.2

In the Evaluation Step if you may get like this!! /content/mask_rcnn_models/mask_rcnn_model.001-2.073964.h5 evaluation using iou_threshold 0.5 is 0.000000

I this case try this.. !pip3 install tensorflow==2.5.0

Gotcha! Thanks.

Hey! I have had the same value error issue even after downgrading TensorFlow to 2.6.0 and Keras to 2.6.0. Do you know the reason?

I don't know the reason !! Its working or NOT?

[asuhag]

Yeah this worked...

Thanks! This did the job for me in colab.

I tried this and still same error

[naseemap47]

@baselsaad123 I did this in very long back. Maybe its due to new version of other packages.
