Unable to connect to server #619

Closed Clement25 closed 6 years ago

Clement25 commented 6 years ago

I typed one command "sudo pip3.6 install git+https://github.com/Xilinx/BNN-PYNQ.git" to install the package of BNN. Firstly it cannot identify the host name so I add "192.30.255.112 github.com" to the host file /etc/hosts. When I run this command again, the error becomes "cannot connect to the server". How can I solve this? I connect the board to the ethernet port on my laptop. My laptop has been connected to a WLAN without proxy. The version of PYNQ is the latest v2.1.

Your board needs to be connected to the internet to do this. If you connect to the Ethernet port of your laptop as described in the setup guide, you have a local network to your laptop only. (You can try to bridge your WiFi and Ethernet connection on your laptop, but I would not suggest you do this as it can be complicated.)

To resolve this, connect your board to a router, or network switch that can serve the board a DHCP address as described in the getting started guide. http://pynq.readthedocs.io/en/v2.1/getting_started.html#ethernet-setup You can then pip install.

Alternatively, download the BNN GitHub as a .zip file. Unzip, and copy to the board. You can then install locally by running: sudo pip3.6 install
