3. Check the SIMD instructions supported by your processor (such as 3DNow!,
SSE, or SSE2) and install dependencies for Hydra. Only libatlas is optimized
for a particular instruction set---for the laptops, we used the sse2 optimized

sudo apt-get -y install libatlas-base-dev liblapack-dev libitpp-dev \
python-scipy python-numpy python-matplotlib
根据上面这个指令安装软件包提示无法安装？不知道怎么解决，求指导！
