Python 在jupyter笔记本中尝试将R与rpy2一起使用时出现UnicodeDecodeError

我试图在同一个笔记本中使用R和python，我遵循了其中的所有步骤，除了从pip安装的rpy2之外（因为.whl方法给出了“rpy2-2.9.5-cp37-cp37m-win_amd64.whl在此平台上不是受支持的轮子。”错误）

在运行此代码的最后一步中：

%%R -i df 
library(ggplot2)

我得到了以下错误日志：

...
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 66: invalid continuation byte

During handling of the above exception, another exception occurred:
...
RInterpreterError: Failed to parse and evaluate line 'library(ggplot2)\n'.
R error message: "'utf-8' codec can't decode byte 0xe9 in position 66: invalid continuation byte"

During handling of the above exception, another exception occurred:
...
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\ABDEL~1.DES\\AppData\\Local\\Temp\\tmpqlksnmtd\\Rplots001.png'

我在anaconda内部有Python 3.8.3、conda 4.9.2、R版本3.6.1，在anaconda外部有R版本4.0
