我已经对该脚本进行了一段时间的修改，似乎无法弄清楚我在做什么错。

我对我认为出错的地方发表了一些评论。因此，这里的实际问题是：将数据转换为因标题消息而出错的绘图时，我会丢失什么？
目的是获取数据集中每个键（传感器＃）的图，x轴上的含氧量值，y轴上的含氧量。
编辑：
根据要求进行回溯：
unsupported operand type(s) for /: 'str' and 'int'
Traceback (most recent call last):
File "testing.py", line 75, in <module>
ax = subax, norm_hist = True)
File "/Users/gabagaba/anaconda/lib/python2.7/site-packages/seaborn/distributions.py", line 192, in distplot
line, = ax.plot(a.mean(), 0)
File "/Users/gabagaba/anaconda/lib/python2.7/site-packages/numpy/core/_methods.py", line 82, in _mean
ret = ret / rcount
TypeError: unsupported operand type(s) for /: 'str' and 'int'
最佳答案
按照@CristiFati的建议，我仔细检查了所有数据输入，最后将所有输入转换为浮点数。这解决了问题。
修改后的代码为：
dataset[count]['Oxy'].append(float(i))
对于脱氧输入也是如此。
关于python - Seaborn distplot:/的不受支持的操作数类型:'str'和'int'，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/48286431/
