尝试以下代码时；我得到错误：
将 numpy 作为 np 导入 pandas 作为 pd 将 matplotlib.pyplot 作为 plt 导入 seaborn 作为 sns
Y = pd.read_csv("C:/Users/Milena/Desktop/CALC/Degree 2020 UN Week/CALC-bitcoin-heur_1_week-degree_moments_all.csv", sep=";", usecols=["Date","z- score k_out_std","RPMA 2","Date","k_out_std","k_out_kurt","RPMA", "k_out_std","k_out_kurt","no_nodes","收盘价 (USD)", "k_out_skew"]) from scipy import stats ax = plt.gca() Y.plot.scatter(y="z-score k_out_std" ,x="Date", alpha=0.3, c="RPMA", colormap="jet",title= "2020 联合国周") plt.show()``
TypeError: 'value' 必须是 str 或 bytes 的实例，而不是浮点数
