Question

过去2天，我一直在尝试运行以下Python脚本，该脚本需要matplotlib来绘制来自传感器的实时数据，但没有成功。

#!/usr/bin/python

import smbus
import math
import matplotlib as mpl
mpl.use('tkagg')
import matplotlib.pyplot as plt


# Power management registers
power_mgmt_1 = 0x6b
power_mgmt_2 = 0x6c
incl = []
plt.ion
def makefig():
    plt.plot(incl,'ro-')

def read_byte(adr):
    return bus.read_byte_data(address, adr)

def read_word(adr):
    high = bus.read_byte_data(address, adr)
    low = bus.read_byte_data(address, adr+1)
    val = (high << 8) + low
    return val

def read_word_2c(adr):
    val = read_word(adr)
    if (val >= 0x8000):
        return -((65535 - val) + 1)
    else:
        return val

def dist(a,b):
    return math.sqrt((a*a)+(b*b))

def get_y_rotation(x,y,z):
    radians = math.atan2(x, dist(y,z))
    return -math.degrees(radians)

def get_x_rotation(x,y,z):
    radians = math.atan2(y, dist(x,z))
    return math.degrees(radians)

bus = smbus.SMBus(1) # or bus = smbus.SMBus(1) for Revision 2 boards
address = 0x68       # This is the address value read via the i2cdetect command
while True:
    # Now wake the 6050 up as it starts in sleep mode
    bus.write_byte_data(address, power_mgmt_1, 0)

    gyro_xout = read_word_2c(0x43)
    gyro_yout = read_word_2c(0x45)
    gyro_zout = read_word_2c(0x47)

    #print ("gyro_xout: ", gyro_xout, " scaled: ", (gyro_xout / 131))
    #print ("gyro_yout: ", gyro_yout, " scaled: ", (gyro_yout / 131))
    #print ("gyro_zout: ", gyro_zout, " scaled: ", (gyro_zout / 131))



    accel_xout = read_word_2c(0x3b)
    accel_yout = read_word_2c(0x3d)
    accel_zout = read_word_2c(0x3f)

    accel_xout_scaled = accel_xout / 16384.0
    accel_yout_scaled = accel_yout / 16384.0
    accel_zout_scaled = accel_zout / 16384.0

    #print ("accel_xout: ", accel_xout, " scaled: ", accel_xout_scaled)
    #print ("accel_yout: ", accel_yout, " scaled: ", accel_yout_scaled)
    #print ("accel_zout: ", accel_zout, " scaled: ", accel_zout_scaled)
    #my_incl = (get_x_rotation(accel_xout_scaled, accel_yout_scaled, accel_zout_scaled))
    #incl.appned(my_incl)
    #drawnow(makefig)
    #plt.pause(0.00001)
   # print ("x rotation: " , '{0:.0f}'.format(my_incl))

    #print ("y rotation: " , get_y_rotation(accel_xout_scaled, accel_yout_scaled, accel_zout_scaled))

运行以上命令时，我从numpy中收到以下错误：

RuntimeError：针对API版本0xc编译的模块，但此版本的numpy为0xa 追溯（最近一次通话）：在第7行的文件“ /home/pi/Desktop/car/car.py” 导入matplotlib.pyplot作为plt 在第32行的“ /usr/local/lib/python3.5/dist-packages/matplotlib/pyplot.py”文件中导入matplotlib.colorbar 在第28行的“ /usr/local/lib/python3.5/dist-packages/matplotlib/colorbar.py”文件中将matplotlib.artist作为martist导入在第11行的“ /usr/local/lib/python3.5/dist-packages/matplotlib/artist.py”文件中从.path导入路径在第17行的“ /usr/local/lib/python3.5/dist-packages/matplotlib/path.py”文件中来自。导入_path，rcParams ImportError：numpy.core.multiarray导入失败

在我看来，我的numpy版本错误。但是仍然在更新numpy，卸载，重新安装，在此处搜索帮助等之后。（不是所有的尝试都一样，每个都作为单独的尝试）我仍然不知道如何解决此问题...

我们将不胜感激。
