我想在JUPYTER中使用pandas2ri，但是tzlocal问题？

Question

每当我尝试在jupyter，python接口中导入pandas2ri时：

from rpy2.robjects import pandas2ri

我收到以下错误：

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-28-cc52694d111a> in <module>()
----> 1 from rpy2.robjects import pandas2ri

/Users/sondosayyash/anaconda/lib/python3.6/site-packages/rpy2/robjects/pandas2ri.py in <module>()
     21 import numpy
     22 import pytz
---> 23 import tzlocal
     24 import warnings
     25 

ModuleNotFoundError: No module named 'tzlocal'

我尝试使用

from dateutil.tz import tzlocal 

但这似乎无法解决问题。

我已经安装了tzlocal，它在我的计算机上。当我在ipython上导入pandas2ri时，没有问题..仅在jupyter环境中调用时才会出现问题。

这是我再次尝试安装tzlocal时收到的消息：

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. 

Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
Requirement already satisfied: tzlocal in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (1.5.1)
Requirement already satisfied: pytz in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from tzlocal) (2017.2)

Answer 1

在 Jupyter 中运行 rpy2 时我遇到了类似的问题。我之前没有安装这个包。我刚刚安装了该软件包，错误就消失了。您可以尝试再次安装该软件包，看看它是否有助于解决您的问题。

pip install tzlocal

我必须补充一点，我使用的是 Python 3.6.8 而不是 2.7
