I see some dead unresolved threads from 2019 and 2020 (unlike Osment). Wondering if there is an update. I’ve got this message WARNING (theano.tensor.blas): Using NumPy C-API based implementation for BLAS functions. This appears common. Pymc3 works but apparently can be sped up. What BLAS must I …

If you type conda search pymc3 --info, the following information appears: pymc3 3.11.2 pyhd8ed1ab_0 ------------------------- file name : pymc3-3.11.2-pyhd8ed1ab_0.tar.bz2 name : pymc3 version : 3.11.2 build : pyhd8ed1ab_0 build number: 0 size : 616 KB license : Apache…

@rosgori , What’s the OS in which you ran these commands? Struggling here to correctly install pymc3 in Windows 10, even by just referencing to conda-forge channel. Same warning reported by @pythonometrist showing up here.

I am using Ubuntu 20.04, using conda (as you can see) and the main channel is conda-forge.

Wow you are fortunate - couldnt get Pymc3 to work on windows at all. Did you just follow the wiki?

For Windows, try creating a new fresh conda environment following the instructions on Installation Guide (Windows) · pymc-devs/pymc3 Wiki · GitHub . I’ve had the same problem with blas in Windows, and this procedure worked for me. Hopefully, it can help you as well. The crucial catch seems to be: i…

@rladeira That’s an inception level twist . Many thanks - will check with pip at the end.

So now numpy shows : blas_info: libraries = ['cblas', 'blas', 'cblas', 'blas'] library_dirs = ['/root/anaconda3/envs/bayes/lib'] include_dirs = ['/root/anaconda3/envs/bayes/include'] language = c define_macros = [('HAVE_CBLAS', None)] blas_opt_info: define_macros = [('NO_ATL…

Wait a minute, did you install conda in the root directory? blas_info: libraries = ['cblas', 'blas', 'cblas', 'blas'] library_dirs = ['/root/anaconda3/envs/bayes/lib'] include_dirs = ['/root/anaconda3/envs/bayes/include'] language = c define_macros = [('HAVE_CBLAS', None)] blas_…
