I am trying to get a simple Blaze example, working on Ubuntu, inside an Anaconda installation (Python 3.3).
import blaze
from blaze import array
from datashape import dshape
# array creation
arr1 = array(3.142)
arr2 = array([[1, 2], [3, 4]])
print(arr1)
print(arr2)
But running gives me this error:
import blaze
File "/root/anaconda/envs/py3k/lib/python3.3/site-packages/blaze/__init__.py", line 10, in <module>
from . import catalog
File "/root/anaconda/envs/py3k/lib/python3.3/site-packages/blaze/catalog/__init__.py", line 4, in <module>
from . import catalog_config
File "/root/anaconda/envs/py3k/lib/python3.3/site-packages/blaze/catalog/catalog_config.py", line 6, in <module>
from .catalog_dir import is_abs_bpath, CatalogCDir
File "/root/anaconda/envs/py3k/lib/python3.3/site-packages/blaze/catalog/catalog_dir.py", line 5, in <module>
from .catalog_arr import load_blaze_array
File "/root/anaconda/envs/py3k/lib/python3.3/site-packages/blaze/catalog/catalog_arr.py", line 9, in <module>
from datashape.type_equation_solver import matches_datashape_pattern
ImportError: No module named 'datashape.type_equation_solver'
However, I am able to import datashape, using
python -c "import datashape"
And when I try to conda install <pkgname>, I get that the dependencies are satisfied. I think that this is related to this question, but I find that advice impenetrable.
Any help is appreciated.
The particular error you're getting looks like it's from blaze being built from a more recent checkout than datashape. If you update both of them to the latest master from github, the blaze import should work.
