9 years ago Actually I was running it in a debugger so added main into buyapple.py - here is the code I used
from datetime import datetime

from zipline.api import order, record, symbol
from zipline import TradingAlgorithm
from zipline.utils.factory import load_from_yahoo
def initialize(context):
pass
def handle_data(context, data):
order(symbol('AAPL'), 10)
record(AAPL=data[symbol('AAPL')].price)
if __name__ == '__main__':
start = datetime(2008, 1, 1, 0, 0, 0, 0, pytz.utc)
end = datetime(2010, 1, 1, 0, 0, 0, 0, pytz.utc)
data = load_from_yahoo(stocks=['AAPL'], indexes={}, start=start,
end=end)
data = data.dropna()
algo = TradingAlgorithm(initialize=initialize,
handle_data=handle_data,
identifiers=['AAPL'])
results = algo.run(data)
results.portfolio_value.plot()it fails at record(AAPL=data[symbol('AAPL')].price), was trying to debug it but couldn't figure out the inheritance.

9 years ago Have a look at my closing comments on the closed thread #707. It turned out I had the wrong version of sqlite3 in the Python library.
The point is unless you guys specify every single component of every single element in Python / anaconda/ whatever necessary to run the latest version of Zipline, your job is impossible. Even clowns like me are capable of following a simple recipe book. And unfortunately the recipe book needs to be wider than just the zipline dependencies contained in requirement.txt
You Quantopians are not suffering from this Key Error and your back tester is zipline. If, therefore, you gave a more complete recipe of every single piece of software and the correct version (for a given operating system such as Windows 8.1) would it not be simpler to track such issues?
Because at present, is it entirely clear where the issue lies? Within zipline? Or within the wider environment in which zipline operates?

9 years ago Yes. That particular issue was solved.Now I am faced with a host of other (hopefully less serious) issues. I'm enjoying the process but clearly it is going to take me quite a while to get the comfort I need before using either Zipline or Quantopian for actual trading.

@beebeed @xingjianpan can I suggest you take the action explained here: http://lambdathefirst.blogspot.com/2011/01/how-to-upgrade-sqlite-that-comes-with.html to ensure you have a recent version of SQLite under the hood.

AnthonyFJGarner

9 years ago The issue in this thread is not resolved for me and I simply thought I would try generating the C files as per
python setup.py build_ext --inplace.
I thought it may have something to do with the current problems in this thread. But It does not. And yes, I'm still getting the Key Error set out above.
I don't think order() is working either. Probably I'm doing something stupid. The code set out below generates no orders:

aapl_order = get_order(context.order_id)
if aapl_order:
# log the order amount and the amount that is filled
message = 'Order for {amount} has {filled} shares filled.'
message = message.format(amount=aapl_order.amount, filled=aapl_order.filled)
log.info(message)
#log.info(order)

algo = TradingAlgorithm(initialize=initialize,

results = algo.run(data)
results.portfolio_value.plot()
pl.show()buyapple.py still generates:

9 years ago for what its worth, I just ran the code above, and it executed fine. Although it seems to lose money, so something must be pretty wrong with the logic!
Sorry you are still having problems Anthony. I'm running fine on 0.80rc1, although I did have a couple of problems installing that. I'm on python 3.4.3, and the pip and conda installers would only install 0.7 so I had to build from github and had an annoying error that my c++ compiler could not be found which I somehow managed to fix. I am contemplating moving to ubuntu in due course, but for now, it is possible to get it running under windows 7 64 bit. It is just a bit of a chore. I do think Quantopian should make this easier. I know that their focus is on their core Quantopian business and that they are no doubt overwhelmed with work. Still, I wonder how many hours they lose on supporting zipline users. I still believe that Docker might make the install process easier to maintain by enabling a whole environment to be created for each platform.

9 years ago Many thanks - given the time I have wasted so far I have nothing to lose by installing the same version of Python as you have and see what happens. The problem is very clearly with the environment which is ridiculously difficult to set up - as you say, the Quantopians could make like much easier for everyone by simplifying this. I have not even begun to code any systems yet since I can't pass go!
Zigguratti
commented
9 years ago Yes, if you create a separate anaconda install and try from scratch, it shouldn't take too long. I'm not entirely sure how I managed to get my C++ compiler installed correctly, but I think if you install some of the same files I did, it should work as it did for me. I have been thinking of posting up what I had to do as a mini 'hacktorial' for anyone who wants to use zipline with external data sources as I am, because there really isn't much documentation on that, and hopefully I'd get better insights from quantopian correcting any errors I have undoubtedly made! It seems pretty cool now that I have it working, although I don't trust it yet and need to go through some of the major parts of the code which will involve learning some OO.
I gather I will have to disable the trading calendar to use non-US stocks which is nearly where I am at ... replacing that for every major market in the world (including all of Europe) just is't going to be practical at this stage! If my sharpe ratios are a little out it doesn't matter too much (not like anyone uses intraday figures in any of these calcluations!), but it does matter if trading days are being skipped due to zipline thinking they are public holidays etc.!

9 years ago Thank you Zigguratti, your procedure has worked for me.
pip install -e C:\Application\Github\Zipline (which is where my zipline is installed on my PC)
Lo and behold, this time all the uninstalled dependencies were installed and any incorrect version was uninstalled and then reinstalled with the correct version.
Here is the point for the Quantopian guys:
Your set up instructions are a hopeless, total mess. Not really your fault since you don't aim to deal with morons such as myself. But my god you could save yourself some problems if you exercised some precision in your instructions and explanations.
I am an ex City securities lawyer so absolute precision was drummed into me many years ago. I hope the above may be of help to someone. The problems are legion for someone new to this game and I reiterate my very strong recommendation that you guys (for your own sake) give a much easier and more explicit set of instructions.
I was initially fooled into downloading Python 2.7 because I thought I had to use Zipline 0.7.0 https://pypi.python.org/pypi/zipline
I then realised Zipline 0.7.0 was an outdated and (for my purposes) hopeless version and so eventually stumbled onto the ability to use the very latest version which I update regularly from github.
I never realised that changing from Python 2.7 to 3.4 would solve my problems....but that's probably because I'm just dumb.
You never know, I might just be able to get on with developing systems in Zipline now......
Zigguratti
commented
9 years ago Great!
In quantopian's defense, they are probably targeting zipline at linux users; hardly anyone does serious development on Windows systems nowadays (I am told). I would recommend moving to e.g. Ubuntu as I have read that the latest versions of many libraries' binaries come to windows late and they don't always compile ... but there will be more people like us who wind up in this situation, and it'll waste Quantopian's resources on support/PR which might otherwise be better spent making quantopian/zipline better! For now, I'm using windows as I have a large list of much more pressing things to master, and grappling with a new environment would be a distraction.
Just one other thing: check out the ipython QT console ... if you aren't already using that, it is a great way to write python code, because you can interact with the data objects as you develop your code ... kind of crucial in figuring out how zipline works. It is slower than running scripts in an ide (e.g. pycharm), but it is so so powerful ... an analogy would be Rstudio if you are at all familiar with that. And these ipython notebooks look pretty darned cool ...
Best,
Carl

9 years ago No problem, nice to meet you Stewart.
Here are the notes I made to myself the other week, should anyone else venture here with similar problems: Installation Version 0.8.0 is best
pip install zipline installs 0.7, which is an old release lacking various pieces of functionality, not least scheduler, required to use pyfolio. So it is worth installing 0.8. Unfortunately, this is non-trivial, especially for non-linux users (but for most people). I am on python 3.4, although only 3.3 is officially supported. How? github
I used github to clone the repo from gitbash:
F:\work\systematic equity\Coding\python\tst\zipline> pip install -e git+https://
github.com/quantopian/zipline.git#egg=zipline Errors
Originally I had an error concerning the building of cython:
skipping'C:\Users\HPLappy\AppData\Local\Temp\pip-build-v6y_t76p\Cython\Cyth
on\Plex\Scanners.c' Cython extension (up-to-date)
building 'Cython.Plex.Scanners' extension
error: Microsoft Visual C++ 10.0 is required (Unable to findvcvarsall.bat). Fix
Googling revealed that this is not an uncommon problem ( http://stackoverflow.com/questions/26473854/python-pip-has-issues-with-path-for-ms-visual-studio-2010-express-for-64-bit-ins ).
The advice seemed to be to install Microsoft visual C++ 2010 express, and to add an environment variable VS90COMNTOOLS which I set to 2013 (not convinced that this made any difference, or that 2013 was the correct value to set; chosen as that was the most recent disctributable C++ library I had installed). (file visual studio 2010 VS10sp1-KB983509.exe, https://support.microsoft.com/en-gb/kb/2977003). I also installed vcredist_x64.exe, C++ redistributable ( https://www.microsoft.com/en-gb/download/details.aspx?id=40784). It seems that actually loading visual studio may have set up the path variables (or something) required to build zipline 0.8.0rc1.

7 years ago Am getting the same error, while installing zipline on python 3.5 virtual env.

7 years ago @BraveNewMath to me it sounds like you're trying to install zipline for Python 3.6. The newest version of conda by default uses Python 3.6, so you'll have to create a new conda env using conda create, that uses Python 3.5
There's more information on the Zipline Install Docs

7 years ago @thomas2004ch I'm sorry, I may have misunderstood which link you're talking about. The only link I saw with a 404 in this thread is the one to the Install Docs (which I edited and corrected, http://zipline.io/install.html).
Which link were you talking about exactly?

7 years ago @FreddieV4 The link I mention is this one in your post: Zipline Install Docs. As I open it I got 404.
The link http://zipline.io/install.html works. But it hasn't told how to overcome the problem by installing the zipline.1.1.1 on Anaconda 3 (Python 3). Are successful to install the zipline 1.1.1 on Anaconda 3?

7 years ago @thomas2004ch You should be able to install zipline on Python 3.4 and 3.5 with Anaconda (I'd recommend installing in a new conda env)

6 years ago 1. I haven't uased the Zip-line since many people say it is not ripe enough to do real-time trading.
2. How did you build your ENV? Do you use Windows or Ubuntu? Where can I find your codes?
