ValueError: [Keras Visualizer] Error while visualizing: <class 'Exception'>

[chaowu2009]

using the following exampe as in the document: from keras import models, layers from keras_visualizer import visualizer

model = models.Sequential([ layers.Dense(64, activation='relu', input_shape=(8,)), layers.Dense(6, activation='softmax'), layers.Dense(32), layers.Dense(9, activation='sigmoid') ])

visualizer(model, file_format='png', view=True)

and got the following error:

ValueError: [Keras Visualizer] Error while visualizing: <class 'Exception'>

windows environment with jupyter notebok.

It seems that the problem is with the graphviz library. Try to install it by other methods or use Google Colab to run this code.
