Why python pandas does not provide Linux whl files -


i wondering why python pandas not provide .whl files pip install on linux. whl files available mac , windows, though. see: https://pypi.python.org/pypi/pandas/0.18.1

i 

pip install pandas

but involves time-consuming process of building source. have continuous-integration system includes pandas build dependency, i'd have benefit of fast install binary .whl file without building source.

armin ronacher discusses @ length. fundamentally, linux distributions not sufficiently uniform , can't depend on presence of particular libraries link against; python library may inconsistent.

you can build own wheel environments using , install them many times like, should work fine continuous integration system:

$ pip wheel pandas collecting pandas   downloading pandas-0.18.1.tar.gz (7.3mb)     100% |████████████████████████████████| 7.3mb 131kb/s  ... built pandas  $ ls pandas* pandas-0.18.1-cp35-cp35m-linux_x86_64.whl  $ pip install pandas-0.18.1-cp35-cp35m-linux_x86_64.whl  processing ./pandas-0.18.1-cp35-cp35m-linux_x86_64.whl ... installed pandas-0.18.1 python-dateutil-2.5.3 pytz-2016.4 six-1.10.0

note numpy provides linux wheel files on pypi. looking inside (they simple zip files) can see bundle usual numpy libraries such lapack_lite plus dependencies (gfortran , openblas in case):

$ unzip -l numpy-1.11.0-cp35-cp35m-manylinux1_x86_64.whl  | grep [.]so  ...  38407360  2016-04-12 21:01   numpy/.libs/libopenblasp-r0-39a31c03.2.18.so   1017104  2016-04-12 21:01   numpy/.libs/libgfortran-ed201abd.so.3.0.0    108200  2016-04-12 21:01   numpy/linalg/lapack_lite.cpython-35m-x86_64-linux-gnu.so ...

by contrast numpy installed o/s has lapack_lite linked /usr/lib/libblas, via debian alternatives system links against optimized libatlas, should have better performance (untested).

looking @ lapack links, using pretty standard libraries, should work on many 64-bit linux systems:

$ ldd lapack_lite.cpython-35m-x86_64-linux-gnu.so      linux-vdso.so.1 =>  (0x00007fffadf7a000)     libopenblasp-r0-39a31c03.2.18.so => /tmp/numpy/linalg/./../.libs/libopenblasp-r0-39a31c03.2.18.so (0x00007f5efb8bc000)     libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f5efb69e000)     libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5efb2d9000)     libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f5efafd3000)     libgfortran-ed201abd.so.3.0.0 => /tmp/numpy/linalg/./../.libs/libgfortran-ed201abd.so.3.0.0 (0x00007f5efacda000)     /lib64/ld-linux-x86-64.so.2 (0x00007f5efe0d4000)

presumably volunteer create wheels pandas well, , keep them date across different versions of python. note pandas .so files link against libpython, somehow numpy avoids doing despite making python calls.

edit 2016-05-25: added instructions building , installing wheels.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
