when using pip3 to install arch and ffn python packages under

Ubuntu16.04LTS system python3.5.2, it is always prompted:
Could not find a version that satisfies the requirement numpy==1.9.3
No matching distribution found for numpy==1.9.3
this error is reported regardless of whether numpy==1.14.3, is installed or numpy==1.9.3 is installed in the system. The installation process and error message are as follows:

at first I thought the 1.9.3 version of numpy, could not be found in ubuntu"s software source, but I could install it manually by using the pip3 install numpy==1.9.3 command, and I still couldn"t solve this problem after I changed the software source
