about the error for 'conda install -c quantopian/label/ci -c quantopian zipline

[Tik Ho Hui]

I have used the above commands 'conda install -c quantopian/label/ci -c quantopian zipline' for installation of new version of zipline, However, it seems unstable that the following errors still happens. May I ask how could I solve for it ?

Any help on this ? I find that the new zipline version has been very unstable, sometimes OK , sometimes not, with much different errors come out !

Hi Tik,

I noticed you're using a conda env called py362. We currently only build packages for Py 3.5 and Py 2.7. Can you try a Py3.5 conda env?

Actually, I am using Python version 3.4, since we need to modify the program for suiting the FX data, so would like to keep on using it ! and I find out that using in Python 3.4 sometimes work, but sometimes not, especially in spooling SPY data. May I ask is there any changes within the source data or source code ?

2 questions 

a.) Can version 3.4 be applied for the case ?

b.) Is there any changes on the source data or server ?

Please help if you can reply ! Thanks !
