Installing on PYNQ 2.3

Hello,

I have tried installing this with the following (as stated in the instructions):
sudo -H pip3.6 install --upgrade git+https://github.com/Xilinx/PYNQ-DL.git

however, this gave the following error
pip3.6: command not found

I believe the new command is pip3 (since this change worked with another git repo), so I changed it to the following:
sudo -H pip3 install --upgrade git+https://github.com/Xilinx/PYNQ-DL.git

This showed the installation was successful and following this, I had rebooted, however, no new notebooks appeared, any advice would but much appreciated.

Problem with Darius-cnn-ip

I download this whole project with to my pynq board and change the overlay path to the right place. When I run the first time, the data printed is the same as darius-cnn-ip.ipynb, so it's loaded right . However, when I explore the detailed parameter, I find many problems.
First, when I print the OFM array, I find many negative number in it??? The input IFM and weight is the same as the demo which is random ranging from 0 to 255. I can't explain why the convolution and max pooling can change positive integer to negtive integer.......
Then, I change the parameter for pooling and run the demo again, I find the OFM does't change. I can't explain why this happens.

You can also find the first problem, just by changing your demo in darius-cnn-ip.ipynb:
for i in range(0, 15, 4): print(hex(ofm[i]))
change to a larger range:
for i in range(0, 159, 4): print(hex(ofm[i]))
and many problems.

You can try different pooling parameter and see if the output OFM is changed.

If my operation is wrong, can you show me the right using process?
