Tensorflow version? #231

Open ZehanDai opened 4 years ago

ZehanDai commented 4 years ago

Hi all,

When I tried the script in this page on test image in reference to the ipynb script below, I got an error: tensorflow.python.framework.errors_impl.InvalidArgumentError: No such callable handle: 140395736213952
while the script reached this line img = visualize_activation(model, layer_idx, filter_indices=20)

I don't have a clue on how to fix it. Is it possibly caused by the tensorflow version? I am using a very old one (tensorflow 1.10.0).

Actually I tried newest version of tensorflow and keras at the beginning. But I came across an issue https://github.com/raghakot/keras-vis/issues/228 and solved by following AniketSawale's advice https://github.com/raghakot/keras-vis/issues/228#issuecomment-670492169

My script is: `from keras.applications import VGG16 from vis.utils import utils from keras import activations

'# Build the VGG16 network with ImageNet weights model = VGG16(weights='imagenet', include_top=True)

'# Utility to search for layer index by name. '# Alternatively we can specify this as -1 since it corresponds to the last layer. layer_idx = utils.find_layer_idx(model, 'predictions')

'# Swap softmax with linear model.layers[layer_idx].activation = activations.linear model = utils.apply_modifications(model)

from vis.visualization import visualize_activation from matplotlib import pyplot as plt import cv2 as cv '# %matplotlib inline plt.rcParams['figure.figsize'] = (18, 6)

'# 20 is the imagenet category for 'ouzel' img = visualize_activation(model, layer_idx, filter_indices=20) '# plt.imshow(img) '# plt.imsave('test.jpg') print(type(img)) '#plt.savefig('test.png')` which is in reference to this ipynb file. https://github.com/raghakot/keras-vis/blob/master/examples/vggnet/activation_maximization.ipynb
