i'm attempting run model in pymc3 takes advantage of theano.dot when performing dot product in multilevel model. however, when attempt import theano get:

python model.py  ... // there's huge output that's looks file  problem occurred during compilation command line below: g++ -shared -g -o3 -fno-math-errno -wno-unused-label -wno-unused-variable -wno-write-strings -wl,-rpath,/home/thauck/miniconda/envs/data/lib -d npy_no_deprecated_api=npy_1_7_api_version -m64 -fpic -i/home/thauck/miniconda/envs/data/lib/python2.7/site-packages/numpy/core/include -i/home/thauck/miniconda/envs/data/include/python2.7 -o /home/thauck/.theano/compiledir_linux-3.14-0.bpo.2-amd64-x86_64-with-debian-7.6--2.7.8-64/tmpkxtyks/b4f7a60b7c9f9a250601326a9fe2016e.so /home/thauck/.theano/compiledir_linux-3.14-0.bpo.2-amd64-x86_64-with-debian-7.6--2.7.8-64/tmpkxtyks/mod.cpp -l/home/thauck/miniconda/envs/data/lib -lpython2.7 -lf77blas -lcblas -latlas  /usr/bin/ld: cannot find -lf77blas /usr/bin/ld: cannot find -lcblas /usr/bin/ld: cannot find -latlas 

i'm running backports-debian-7-wheezy-v20140904.

conda:

current conda install:

i have tried, after looking @ various problem:

theano_flags=blas.ldflags="-l/usr/lib/ -lblas" python model.py 

this seg faults.

also, appears have blas directories in /usr/lib.

(data)thauck@ds-th:/usr/lib$ ls | grep blas libblas.a libblas.so libblas.so.3 libblas.so.3gf libopenblas.so.0 openblas-base 

edit:

the cause of breaks mvnormal in pymc3.

i suppose have old version of theano, if we can't find or detect how link again blas, have fallback not cause crash, cause warning.

update theano development version.

if installed via conda, remove first, update:

pip install --upgrade --no-deps git+git://github.com/theano/theano.git 

or

pip install --upgrade --no-deps git+git://github.com/theano/theano.git --user
