I am using PYNQ-Z2, with latest image file. Here default python version is Python 3.6.

  1. I tried to install Tensorflow and keras but i cann’t able to do it.
  2. I tried using Dropbox - TensorFlow_Installation_on_PYNQ_Nov_6_2018.pdf - Simplify your life This tutorial to use pynq z1 with python 3.4 image in pynq z2 also, but cannt able to install tensorflow shows the error as need python>=3.6. But i cannt install tf in python 3.6 also.

Please, need help. Thanks in advance

Hi Sanjay, I am trying to install tensorflow to infer an existing model on PYNQ Z2.
Did you have any luck installing it? If you did, do help a brother out :smile:

I tried with the approch you did but it cant install that tensor flow.
Then i followed this repo:

this did install tensorflow but it gave be the following import error log.

xilinx@pynq:$ python3 --version
