    GennericHeader = fh.read(32)
    SiteCon = fh.read(128)#站点配置模块
    TaskCon = fh.read(256)#任务配置快
    ScanStartTime = np.frombuffer(TaskCon,'i',1,172)
    ScanStartTime = str(datetime.datetime.utcfromtimestamp(ScanStartTime))
    CutNumber = np.frombuffer(TaskCon,'i',1,176)
    print(ScanStartTime)

报错TypeError: only integer scalar arrays can be converted to a scalar index，错在ScanStartTime = str(datetime.datetime.utcfromtimestamp(ScanStartTime))这行，实在不懂

 

Answer 1

将一维数组转化为列表，然后可以进行转换：

ScanStartTime = [str(datetime.datetime.utcfromtimestamp(x)) for x in ScanStartTime.tolist()]
