ImportError: cannot import name 'Datastream'
dhodod opened this issue · 9 comments
Hi,
I'm trying to set up pydatastream under anaconda. I have successfully upgraded pandas and installed suds-py3 and pydatasteam-0.4.0 using pip. When I enter "from pydatastream import Datastream" on the python command line or in a jupyter notebook I get the error in the subject line. Is this a bug or am I missing a step in the setup?
Hello,
this is indeed very strange. Could you please show the full traceback? And also: does import pydatastream fail with the same error?
BTW, are you using Python 3.x?
Best
Vladimir
Hi,
Thanks for getting back to me. Yes, I'm using Python 3.5.
The full traceback is here:
from pydatastream import Datastream
Traceback (most recent call last):
File "", line 1, in
ImportError: cannot import name 'Datastream'
The simple import doesn't throw an error message:
import pydatastream
The pip install appears to show that all the dependencies are in place:
iMac:~ dhodod$ pip install -e ./Downloads/pydatastream-master --upgrade

I'm trying it here on a mac but I had a similar problem on a Windows machine.

Thanks, David.
Honestly I'm a bit confused. Could it be some python-3 specific issue (e.g. caused by the line from pydatastream import * inside __init__.py)? I've never worked with python 3.x so I could only guess at the moment...
And what if you do:
import pydatastream as pds
DWE = pds.Datastream(username="DS:XXXX000", password="XXX000")
instead of from pydatastream import Datastream? If it does not work - could you please tell me what do you see if you do (in IPython or jupyter notebook) import pydatastream as pds and then type pds. and hit "Tab"?
Hi Vladimir,
Sorry for the delay in replying.
I found the solution thanks to your last post. I used the 2to3 conversion utility and now it all works beautifully.
2to3 ./Downloads/pydatastream-master -w
Thanks for your help - it's much appreciated.
Best regards,
David
Hello David,
I used 2to3 and pushed changes here. Now changes are on the pypi as well and should be retrieved with pip/pip3.
Could I ask you to do a clean install via
pip install pydatastream
(or pip3 if you use it)? I would appreciate if you could check/confirm that now installation works fine.
Thanks
Vladimir
Hi Vladimir,
I won't have a chance to verify this for a few days but I will get back to you when I can.
Thanks,
David

Sure, no rush - whenever you have time!
Works on WinPython 3.5.1.2
Hi Vladimir,
The new version 0.4.1 worked perfectly for me too. Thanks for updating it.
Best regards,
David
