         If “–recursive” is not added here, the default caffe will not be downloaded!

The reference is the step-by-step tutorial.
I met one error:

To solve it, two steps are necessary:

You know, the ubuntu system in my Great Alienware is not healthy. Many functions are not working well, including the wifi connection. It is impossible to connect to a new wifi using the graphical interface. I will get error like:

I solved the connection issue using

Reference

1. 1. 1. Determine the name of the wifi. In many tutorials, they directly call their wifi “wlan0”. However, the name is different on my machine. Run the following command:
         
         (base) xiaoxu@chuan:~$ nmcli d DEVICE TYPE STATE CONNECTION wlp4s0 wifi disconnected -- enp5s0 ethernet unavailable -- lo loopback unmanaged --

         1 2 3 4 5

         (base) xiaoxu@chuan:~$ nmcli d DEVICE  TYPE      STATE         CONNECTION wlp4s0  wifi      disconnected  --         enp5s0  ethernet  unavailable   --         lo      loopback  unmanaged     --

         
         The name of my wifi is “wlp4s0”.
      2. List the wifi networks

      3. choose the wifi you want to connect to, and run the following commend:
         
         (base) xiaoxu@chuan:~$ nmcli d wifi connect ** password **

         1	(base) xiaoxu@chuan:~$ nmcli d wifi connect ** password **

      4.  Check whether the wifi is connected:
         
         (base) xiaoxu@chuan:~$ nmcli d DEVICE TYPE STATE CONNECTION wlp4s0 wifi connected NETGEAR91 1 enp5s0 ethernet unavailable -- lo loopback unmanaged --

         1 2 3 4 5

         (base) xiaoxu@chuan:~$ nmcli d DEVICE  TYPE      STATE        CONNECTION   wlp4s0  wifi      connected    NETGEAR91 1 enp5s0  ethernet  unavailable  --           lo      loopback  unmanaged    --

      5.  Notice: Actually in my desktop I still see an icon as no connection, but actually it is connected!
