5 min readThere are several ways to speed up the compile time of TensorFlow. One approach is to use a pre-built binary of TensorFlow instead of compiling it from source. This can significantly reduce the time it takes to set up your TensorFlow environment. Another tip is to enable parallel builds by using the "-j" flag when compiling. Additionally, you can use distributed computing resources or GPUs to accelerate the compilation process.

Next, you can create a new layer using the desired architecture and add it to the existing model using the model.add() method. Make sure to freeze the weights of the pre-trained layers by setting layer.trainable = False before compiling the model.
