I am wondering if there is any way to install Keras on Pynq Z1. I have seen some other posts but nothing that I could do successfully. I was able to install tensorflow 0.11.0 but it does not contain Keras. Any help?

[image] Installing Keras on PYNQ Support If you expect someone to help, you should try to provide as much information as you can about your setup, the problem, what you have already tried, details about the problem(s) you encountered and any other relevant info. Cathal [image] Tensorflow and Keras on Pynq Z1 Support Hi, is there anybody that successfully built Tensorflow and Keras libraries for Pynq Z1? Thank you. Cathal

Yes I have seen all the previous posts, I was hoping there might be some new information since its been about a year. Sorry for the lack of info. I tried installing by the instructions on this post: Error install Tensorflow I managed to install tensorflow but only version 0.9.0 using: wget https://github.com/samjabrahams/tensorflow-on-raspberry-pi/releases/download/v0.9.0/tensorflow-0.9.0-py3-none-any.whl /usr/bin/python3 -m pip install tensorflow-0.9.0-py3-none-any.whl I was able to install version 0.9.0 and version 0.11.0 using same instructions but neither of these versions have Keras. (Does anyone know why the files ending with “none-any.whl” work, but the files ending with “linux-armv7l.whl” don’t work? Unfortunately, further releases didn’t have this ending.) I also tried installing using these PDF instructions by logictronix: TensorFlow Installation on PYNQ FPGA Board It says by installing an older pynq image you can install tensorflow 1.1.0. I tried following the tutorial by installing the 2016 image on the Pynq. After installing the image, the python version is 3.4.3+ Next I tried to install the tensorflow 1.1.0 from samjabrahams github link, but I got an error saying I need to upgrade pip, and after upgrading I got an error saying I need Python 3.5 I downloaded Python 3.5 but got stuck on setting the alias to have pip3 run from python 3.5 instead of 3.4.

I am still trying to figure out how the alias works, I tried changing it and messed up the links and had to re-image the pynq again. Thank you for your help.

I have tried to install tensorflow on arm/aarch64 images but found the compilation process very frustrating. The only success I had was to install tensorflow-lite on edge devices. For later versions of tensorflow (like 0.60+) you need bazel, while bootstrapping bazel itself requires you to use the same QEMU environment that we used to build the SD card image.
