ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or

简介: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or

今天python提示这样一个错误:

#数据是这样来的
# features = np.asarray(features_array)
# 出错语句:
if (features == None):
    return
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

 这意思就是说,如果是数组,不能这样判断。需要a.all()判断。


 如果是None,那么怎么办?所以吾干脆加了个初始化标志来处理这个问题。


......
InitedFlag=False
InitedFlag=True
if (InitedFlag == False):
    return
