Just a standard example gives an error:
from fredapi import Fred
fred = Fred(api_key='..')
data = fred.get_series('GDP')

tried restarting and playing around with various date import commands, but the simple code

gives the error output:

Traceback (most recent call last):
File "", line 254, in run_nodebug
File "..FredDL.py", line 32, in

that's weird - this actually works fine for me. What version of fredapi are you using?

[mortada]

Oh ... I think this is probably because you are on an older version of pandas, what's your pandas version?

[mortada]

@ErkanCDU upgrading to fredapi 0.3.6 should fix your issue.

Hi,

thanks for the quick comments. I am now convinced that something is wrong with my system. After reinstalling the packages, a different error pops up. I will let you know when I have found the solution

Ah I see, does seem like a problem on your system. I'd recommend using Anaconda to manage your python modules https://store.continuum.io/cshop/anaconda/

[ErkanCDU]

The version control was indeed the issue, after reinstalling everything (via Anaconda as you suggested, it works now). Thanks. Case closed.
