blosc/bloscpack dependency

[thequackdaddy]

Hello,

I was trying to install bloscpack and noticed that setup.py has the following lines...

install_requires = [
    'blosc==1.2.7',
    'numpy',
    'six',
]

However, blosc appears to currently be at version 1.2.9dev0. Using pip/conda I wasn't able to install it either.

Is it safe to just edit the requirements to be blosc>=1.2.7?

You may try this at your own risk. Last time I tried a blosc > 1.2.7 many of the unit and or system tests were failing. However, these are very very picky at times since they check exact binary output and compression ratios -- so you may get away with using 1.2.9. It's hard to say for sure. 1.2.7 is likely to result in a fully passing test-suite. Let me know if 1.2.9 works for you.

Right. I guess the problem is that I am unable to install blosc==1.2.7 on my Windows computer

I have Anaconda 2.5 (Python 3.5.1) with Visual Studio community edition. I can compile and install 1.2.8 (or 1.2.9dev0 from github) with no problems. With 1.2.7, pip install blosc==1.2.7 gives me all this nastiness....

Both 1.2.8 and 1.2.9dev0 seem to work just fine. (I'm using these while playing with castra).

Thanks for reporting. I suggest you open a ticket for this with the python-blosc project. As for installing bloscpack, feel free to clone the source code, remove the lines regarding the dependency and installing it. It should be fine if you just want to play around.
