import pandas
df = pandas.read_excel(open('Test.csv','rb'), sheetname='Sheet 1')
grouped = df.groupby('Date (IT)')

Answer 1

看起来您的Date (IT)列包含混合值（字符串和整数，日期或缺失值）。因此，当熊猫尝试比较每个值时，它会因为类型不同而失败。请查看列数据，并确保所有数据均采用有效格式。

Answer 2

我目前尚未安装PyCharm，但可以在命令行中尝试运行：

pip uninstall pandas

随后是重新安装：pip install pandas

或者您始终可以尝试从PyCharm运行它。它将自动建议安装缺少的软件包。
