Problem in Installation

[ravii-github]

Hi,

I wanted to try the QSTrader application. My environment details as below OS: Ubuntu Version: Ubuntu 14.04.5 LTS

First 4 commands (as below) worked without any problems mkdir -p ~/venv/qstraderp3 cd ~/venv/qstraderp3 virtualenv --no-site-packages -p /usr/bin/python3 . source ~/venv/qstraderp3/bin/activate

When I execute the next command pip install git+https://github.com/mhallsmoore/qstrader.git

I get the following and ends with an error Downloading/unpacking git+https://github.com/hallsmoore/qstrader.git Cloning https://github.com/hallsmoore/qstrader.git to /tmp/pip-rq7vfehj-build Cleaning up... Cannot find command 'git' Storing debug log for failure in /home/ubuntu/.pip/pip.log

May I understand the problem and help me with a solution.

Thanks

Try

git clone https://github.com/hallsmoore/qstrader.git
cd qstrader
python setup.py install

[ravii-github]

Thanks for the response. I tried the first command and got the below error remote: Repository not found. Note: I am in the directory ~/venv/qstraderp3

[ravii-github]

I also tried the below $ pip install git+git://github.com/mhallsmoore/qstrader.git

Still ended up in error Command python setup.py egg_info failed with error code 1 in /home/ubuntu/venv/q straderp3/build/pandas Storing debug log for failure in /home/ubuntu/.pip/pip.log

[femtotrader]

Sorry this is

git clone https://github.com/mhallsmoore/qstrader.git

[ravii-github]

That worked but had errors in this command "python setup.py install"

Issue in installing numpy>=1.7.0 Error Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

Followed the below steps 1 Executed "pip install git+https://bitbucket.org/pypy/numpy.git"" Failure RuntimeError: A PyPy interpreter is required Command python setup.py egg_info failed with error code 1 in /tmp/pip-8j5q0l9q-b uild

Any help !!

Hi Ravii,

Can you let me know exactly how you installed Python/virtualenv initially on your Ubuntu setup, prior to attempting to install QSTrader? I'm also using 14.04 LTS.

Cheers,

Mike.

[ravii-github]

Hi Mike, In this version of Ubuntu, python was pre installed. Virtual env was setup using the below command virtualenv --no-site-packages -p /usr/bin/python3 .

Let me know if I missed anything

[mhallsmoore]

Hi Ravii,

I think I had a similar issue a while back and I fixed it by trying this: virtualenv --no-site-packages -p python3 .

i.e. remove the /usr/bin from the latter -p option. Try it in a new virtualenv directory and see what happens.

Perhaps before trying to install QSTrader (but once you've tried the new virtualenv command), see if you can simply install

pip install numpy

If you can get NumPy compiled, then we're probably halfway there!

Cheers,

Mike.

[ravii-github]

Thanks Mike,

Both worked. When I installed numpy I got the below message "Requirement already satisfied (use --upgrade to upgrade): numpy in /usr/lib/python2.7/dist-packages"

I am planning to install qstrader3

[ravii-github]

I got the below error while installing qstrader3 [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/test-easy-install-18829.write-test' Seems like its on version 2.7 of python. Should I upgrade ?

Hi, Any help ?

[ryankennedyio]

@ravii-github You might have just needed sudo on the command ? As it sounds like a permissions issue

[ravii-github]

@ryankennedyio Thanks mate. That worked and command executed successfully.

When I executed the next one pip install -r https://raw.githubusercontent.com/mhallsmoore/qstrader/master/requirements.txt I got the below error Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/matplotlib

What does this mean ?

Thanks

[ravii-github]

I got the issue resolved by the following command sudo apt-get install libfreetype6-dev libxft-dev

However when I tried to execute the backtest with the command python buy_and_hold_backtest.py

I got the below error ImportError: No module named click

Pls help

[bzillins]

click seems to be a package on pypi https://pypi.python.org/pypi/click . You can try issuing the following:

sudo pip install click

[ravii-github]

@bzillins Thanks, installed that package.

Now, I am missing the module "munch" referred in the file settings.py I cant locate the folder as mentioned in line 5 from munch import munchify, unmunchify

[wanageeska]

@ravii-github Munch is another package on pypi https://pypi.python.org/pypi/munch/ Use the same method as you used for Click.

[ravii-github]

@wanageeska Thanks. I also installed the packages enum and multipledispatch along with Munch.

But, when I tried to install "buy_and_hold" i have the below error

Could not find any downloads that satisfy the requirement buy-and-hold Cleaning up... No distributions at all found for buy-and-hold

[wanageeska]

@ravii-github I'm not sure I understand what you mean by installing 'buy-and-hold'. I'm assuming you have tried to pip install. This is not required. The last I checked, 'buy-and-hold-backtest.py' is a sample script contained within the qstrader repo. Provided you have all of the dependencies installed as per the requirements.txt, you can then run the sample strategies from the command line, eg:

python buy_and_hold_backtest.py

The other sample strategies can be run in the same way, eg:

python moving-average-cross-backtest.py

The readme outlines the required steps in more detail.

[ravii-github]

@wanageeska When I tried "python buy_and_hold_backtest.py", I got the error ImportError: No module named buy_and_hold

I just assumed it could be another module and tried the same as Munch. Now I understand However I could see necessary files in the "strategy" folder. Not sure what is wrong.

But I dont see any files with the name "moving-average-cross-backtest.py"
