错误提示 "need at least one array to concatenate" 表明在调用 concatenate 函数时,没有提供任何数组作为参数。这是因为在 concatenate 函数中,至少需要一个数组来进行拼接操作。 2. 检查代码调用 需要检查你的代码中调用 np.concatenate() 的部分,确认是否有数组作为参数传递给该函数。例如,正确的调用方式应该是这...
ValueError: need at least one array to concatenate 我分析的原因: 这个报错是因为使用了 plt.savefig 函数来保存图像,但是图像为空 图像为什么为空是因为我画散点图时设置参数错误 ax.scatter 函数是负责在子图上画散点 其中的 s 参数是表示散点的大小,我对该参数赋值时有负数,故导致子图没有画成功,因此 plt...
