[√] Check that you are up-to-date with the master branch of keras-vis. You can update with:
pip install git+git://github.com/raghakot/keras-vis.git --upgrade --no-deps -
[√] If running on TensorFlow, check that you are up-to-date with the latest version. The installation instructions can be found here.
-
If running on Theano, check that you are up-to-date with the master branch of Theano. You can update with:
pip install git+git://github.com/Theano/Theano.git --upgrade --no-deps -
Provide a link to a GitHub Gist of a Python script that can reproduce your issue (or just copy the script here if it is short).
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
