Some install problem the following information for reference:

  (1)-------libf77blas.so.3-----------------------------------------
  from scipy.linalg import _fblas
  ImportError: libf77blas.so.3: cannot open shared object file: No such file or directory

  problem solved:
  First of all, for libf77blas.so.3, you have to install ATLAS, something like sudo apt-get install libatlas-base-dev

  $sudo apt-get install libatlas-base-dev
  (2)-----------------------------------------
  Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 265, in open
  self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
  FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyS0'

  problem solved:

  (1)menu->perference->Raspberry pi Configuration->Serial Port(Enable)
  (2)reboot:
  (3)$ls -l /dev/ttyS0
        crw--w---- 1 root tty       4, 64 Nov  1 04:21 /dev/ttyS0

How to Enable RPi UART port:

Enable UART:

  1:[MainMenu] -> [Preferences] -> [Raspberry Pi Configuration]

MainMenu 1

  2:Select [Interface Tab] in Raspberry Pi Configuration

  3:Enable Serial Port: Check radio RadioButton

MainMenu 1

  4:List tty Device

  $ls /dev/tty*
  $sudo chmod +666 /dev/ttyS0
  or 
  $sudo chmod +666 /dev/ttyAMA0

  Reboot

MainMenu 1

UART Still can not work, Please check cmdline.txt

$cat /boot/cmdline.txt

if you find the console=serial0,115200 in cmdline.txt. please use raspi-config to remove it.

$sudo raspi-config 
then reboot
