# initialize LeNet and then write the network architecture To see how easy it is, open a new file, name it visualize_architecture.py and insert the following code: # import the necessary packagesįrom import plot_model Visualizing network architectures with Keras is incredibly simple.
$ pip install pydot Visualizing Keras Networks Once the graphviz library is installed, we need to install two Python packages: $ pip install graphviz While on macOS, we can install graphviz via Homebrew: $ brew install graphviz On Ubuntu, this is as simple as: $ sudo apt-get install graphviz To construct a graph of our network and save it to disk using Keras, we need to install the graphviz prerequisite: Gain access to Jupyter Notebooks for this tutorial and other PyImageSearch guides that are pre-configured to run on Google Colab’s ecosystem right in your web browser! No installation required.Īnd best of all, these Jupyter Notebooks will run on Windows, macOS, and Linux! Installing graphviz and pydot Then join PyImageSearch University today!

If you need help configuring your development environment for OpenCV, I highly recommend that you read my pip install OpenCV guide - it will have you up and running in a matter of minutes. Luckily, OpenCV is pip-installable: $ pip install opencv-contrib-python To follow this guide, you need to have the OpenCV library installed on your system. In the remainder of this tutorial, I’ll help you visualize your own network architectures to avoid these types of problematic situations. Instead, a CNN very well may train and obtain reasonable results even with an incorrect layer ordering, but if you don’t realize that this bug has happened, you might report your results thinking you did one thing, but in reality did another. Whenever implementing a network architecture, I suggest you visualize the network architecture after every block of CONV and POOL layers, which will enable you to validate your assumptions (and more importantly, catch “bugs” in the network early on).īugs in Convolutional Neural Networks are not like other logic bugs in applications resulting from edge cases.
