因为subprocess.call调用cmd .exe flash off，只返回值'1'，表示运行错误。我只是截图解释。
在win cmd下，它运行良好。为什么它在subprocess.call中断？

H:\calibration\bgcclimb>pointbgc.exe .\ini\spinup\t59_13_79_29_11_80_8.ini
在Python中使用subproceess.call：返回值'1'，而不是'0'
subprocess.call([r'H:\calibration\bgcclimb\pointbgc.exe',r'.\ini\spinup\t59_13_79_29_11_80_8.ini'])
Out[7]: 1
使用subprocess.Popen检查stderr：
process = subprocess.Popen([r'H:\calibration\bgcclimb\pointbgc.exe',r'.\ini\spinup\t59_13_79_29_11_80_8.ini'], shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
out, err = process.communicate()
errcode = process.returncode
err
Out[3]: b"Can't open .\\ini\\spinup\\t59_13_79_29_11_80_8.ini for ascii read ... Exiting\r\nError opening init file, pointbgc.c\r\n"
