Dear author,
the code 7_cat_vs_dog_bottleneck.py
I encountered an error when running your code. This issue is related to the line 51. However, after changing categorical_crossentropy to binary_crossentropy the problem was solved.
Could you check this problem?
Thanks very much!
Best,
Helen
Hi!
In Chapter 2, 2_mnist_cnn.py, I am getting an InvalidArgumentError.
Can someone please have a look at it and find out why it's happening?
Thanks
I cannot find out 'fc_model.h5'.
Where can i find it out?
Dear author,
I have encountered an error when running your code for modelling FCN for segmentation.
Traceback (most recent call last): File "d:\git\Deep-Learning-for-Computer-Vision\Chapter05\3_satellite.py", line 14, in <module> resnet50_model = ResNet50(include_top=False, weights='imagenet', input_tensor=input_tensor) File "C:\Users\gesu270495\AppData\Local\Programs\Python\Python36\lib\site-packages\keras_applications\resnet50.py", line 212, in ResNet50 x = layers.ZeroPadding2D(padding=(3, 3), name='conv1_pad')(img_input) File "C:\Users\gesu270495\AppData\Local\Programs\Python\Python36\lib\site-packages\keras\engine\base_layer.py", line 446, in __call__ previous_mask = _collect_previous_mask(inputs) File "C:\Users\gesu270495\AppData\Local\Programs\Python\Python36\lib\site-packages\keras\engine\base_layer.py", line 1328, in _collect_previous_mask mask = node.output_masks[tensor_index] AttributeError: 'Node' object has no attribute 'output_masks'
So far, I haven't been able to fix it. Any suggestions about what might cause this error would help.
Best Regards,
Shirll
In chapter 6, when running 5_fiducial_points.py, error happens.
How to import it?
Dear author;
I got this error when running the code:
ValueError: Negative dimension size caused by subtracting 3 from 2 for 'conv2d_93/Conv2D' (op: 'Conv2D') with input shapes: [?,2,2,256], [3,3,256,512].
and also :
TypeError: init() missing 1 required positional argument: 'kernel_size'

In Chapter 8, I modified vgg16_avg.py to match keras 2.0.
But I get an error on line 100 in 1_style_transfer.py, but I do not know how to fix it.
line 100 is as follows,
style_loss = sum(style_mse_loss(l1[0], l2[0]) for l1, l2 in zip(style_features, style_targets))
And the error is as follows,
ValueError: Dimensions must be equal, but are 64 and 128 for 'add_1' (op: 'Add') with input shapes: [64], [128].
I would appreciate it if you could tell me how to fix the error.
