Win10系统使用Usb转GPIO模块，Python导入Pygpio调用报错

我的代码如下
import sys
from sys import argv,exit
from pygpio import *

IN1 = 1
def setup_gpio():
BaseGPIO.setup(IN1, OUT)

if name == 'main':
app = QApplication(sys.argv)
setup_gpio()
sys.exit(app.exec_())
出现如下报错
File "D:\lpcj\Qt-Camera\lpcj3.py", line 166, in setup_gpio
BaseGPIO.setup(IN1, OUT)

setup() missing positional argument:'mode'

打开pygpio目录下的gpio.py文件，有如下内容
import Adafruit_GPIO.Platform as Platform

OUT = 0
IN = 1
HIGH = True
LOW = False

RISING = 1
FALLING = 2
BOTH = 3

PUD_OFF = 0
PUD_DOWN = 1
PUD_UP = 2
class BaseGPIO(object):
"""Base class for implementing simple digital IO for a platform.
Implementors are expected to subclass from this and provide an implementation
of the setup, output, and input functions."""

def setup(self,pin,mode,pull_up_down=PUD_OFF):
    """Set the input or output mode for a specified pin.  Mode should be
    either OUT or IN."""
    raise NotImplementedError

这个setup()里的第一个参数为什么是self，怎么赋值，我的pin是IN1，mode是OUT，为什么说我缺少mode参数？

self不需要你赋值 那是代表类实例本身的
你不应该调用BaseGPIO 你应该调用RPiGPIOAdapter
