ImportError: cannot import name 'Timestamp'

Question

I have ggplot successfully installed in my python 3.6.3 using the code below:

conda install -c conda-forge ggplot 

But when I import it in my notebook using the code below, I get an error:

from ggplot import *
ImportError: cannot import name 'Timestamp'

I would appreciate any idea on how I can solve this problem.

Answer 1

I have encountered the same problem.

Please go to .../site-packages/ggplot/stats/smoothers.py and change

from pandas.lib import Timestamp

to

from pandas import Timestamp

and save.

Answer 2

@Liaoming999 is correct but adding more changes to resolve this problem:

1. Open file ../site-packages/ggplot/stats/smoothers.py
2. Change from pandas.lib import Timestamp to from pandas import Timestamp in line 4
3. Change pd.tslib.Timestamp to pd.Timestamp in line 14.
4. Save the file
5. Open file ../site-packages/ggplot/utils.py and goto line 81 and do the same as step 3. Thanks to @wmsmith for this tip.

p.s.: General advise is to use Anaconda or some Virtual env.

Answer 3

I encountered the same problem after upgrading to pandas 0.23 on a databricks server.

Had to come up with this command-line solution using the unix sed tool:

cd .../python/lib/python3.5/site-packages/ggplot/stats/
sed -i 's/pandas.lib/pandas/g' smoothers.py
