pip installation of pyqstrat fails on windows 10; missing .h files

[multiquant]

I installed pyqstrat on windows 10, and ran pip to install it . I installed Microsoft Visual Studio build tools prior to running pip. I get the following error during pip install:

C:\Users\Andrei\AppData\Local\Temp\pip-build-dww8vkw7\pyqstrat\pyqstrat\cpp\arrow_writer.hpp(8): fatal error C1083: Cannot open include file: 'arrow/api.h': No such file or directory

The error essentially says that file 'arrow/api.h' cannot be found. I looked inside the archive pyqstrat-0.2.15.tar.gz (which I unzipped) and I see a file arrow.hpp inside cpp folder , that has a line #include <arrow/api.h> in it. However there is no folder "arrow" or file api.h anywhere inside the archive. So it appears that some C++ files (headers) and folders that contain them are missing from the installation archive

Hi

Please make sure you have boost-cpp and arrow-cpp installed and the version of arrow-cpp is greater than or equal to 0.12.1.

See the readme at https://github.com/abbass2/pyqstrat https://github.com/abbass2/pyqstrat for details. Run the following for your anaconda environment.

conda install boost-cpp arrow-cpp -c conda-forge

Best,

Sal

Sal hello

Thank you for your advice. I implemented it following all instructions on installation. The install is fine now , there are no errors. However when I run the Jupyter notebook that you have provided, I get the following error , that is produced by the line "import pyqstrat":

ImportError Traceback (most recent call last) in 7 import os 8 ----> 9 import pyqstrat as pq 10 11 pq.set_defaults() # Set some display defaults to make dataframes and plots easier to look at ~\Anaconda3\lib\site-packages\pyqstrat__init__.py in 10 from pyqstrat.plot import 11 from pyqstrat.evaluator import ---> 12 from pyqstrat.pyqstrat_cpp import 13 from pyqstrat.marketdata_processor import 14 ImportError: DLL load failed: The specified procedure could not be found.

My setup is this :

1) Windows 10

2) Anaconda 5.0.1

3) Pyarrow 0.13.0

4) Python 3.6.3

Would you have any advice on what to do?

Should I post this problem on Github?

With best regards

Andrei Gerasimov
