ValueError: Input 0 of layer conv1 is incompatible with the layer: : expected min_ndim=4, found ndim=3. Full shape received: [32, 64, 3]

while running the command >python nets/test.py -g -v -se -m ./model/c3ae_model_v2_151_4.301724-0.962, I am getting a value error.

ValueError: Input 0 of layer conv1 is incompatible with the layer: : expected min_ndim=4, found ndim=3. Full shape received: [32, 64, 3]

Any help is much appreciated!

Can you provide your enviroments (tensorflow version) ? I have test it locally (tensorflow 2.1), and work well.

you can find that your inputs may invalid which needs (1, 64, 64, 3) and your inputs size shows it as (32, 64, 3).

Thanks for the quick reply @StevenBanama .

I have tensorflow 2.3.

I am new to these things and just trying to test it on one of the test images.

You can do print the shape img before lines 102 like this to check the inputs. ''' print(img.shape) '''

Firstly you can update your local repos. And then run it as below.

python nets/test.py -g -se -i assets/timg.jpg -m ./model/c3ae_model_v2_151_4.301724-0.962

Have you resolved it? Feeling free to promote the issue~

i have found the solution, so you just need to np.expand_dim() each image in tri_imgs array.. then pass tri_imgs array to model.predict(). it will work fine

        age_label, gender_label = age[-1][-1], "unknown"
    else:
       raise Exception("fatal result: %s"%result)
    cv2.putText(new_bd_img, '%s %s'%(int(age_label), gender_label), (padding + int(bounds[pidx][0]), padding + int(bounds[pidx][1])), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (25, 2, 175), 2)
if save_image:
    print(result)
    cv2.imwrite("igg.jpg", new_bd_img)
return new_bd_img, (age_label, gender_label)

using these codes to replace the source file，can solve the problem
