I just started using virtualenv for my existing python project and ran into some trouble...
When I try to import the following
from scipy.sparse.linalg import spsolve
it causes an import error if a virtualenv is activated
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

ImportError: .../lib/python2.7/site-packages/scipy/sparse/linalg/dsolve/_superlu.so: undefined symbol: dtrsm_
When I use the global site-packages I don't get the error.
Can someone help me?
It appears there's some sort of trouble between numpy-1.10.2 and scipy (see here). Try the following (it fixed it for me):
(ve) $ pip install numpy==1.10.1
(ve) $ pip install --upgrade --force-reinstall scipy
(ve) $ python
>>> from scipy.sparse.linalg import spsolve

I'm attempting to load a numpy library into python 3.8.0 on Ubuntu.
from numpy import loadtxt
gives a very verbose error, without a solution:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/numpy/core/__init__.py", line 16, in <module>
from . import multiarray
ImportError: cannot import name 'multiarray' from partially initialized module 'numpy.core' (most likely due to a circular import) (/usr/lib/python3/dist-packages/numpy/core/__init__.py)
During handling of the above exception, another exception occurred:

ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: cannot import name 'multiarray' from partially initialized module 'numpy.core' (most likely due to a circular import) (/usr/lib/python3/dist-packages/numpy/core/__init__.py)
Based on advice that I saw on Python circular importing? I changed the import line to import all of numpy:
import numpy
but this gives the same error.
As the error suggests, I tried re-installing numpy with pip:
sudo pip install --upgrade --force-reinstall numpy
the same error happens with
sudo pip3 install --upgrade --force-reinstall numpy
which worked, and installed numpy-1.19.5. However, this didn't fix the import problem.
I tried implementing a solution from https://github.com/numpy/numpy/issues/9047 which involves setting
export PYTHONPATH=/usr/lib/python3/dist-packages/$PYTHONPATH in ~/.bashrc, but this failed as well.
How can I import numpy?
The problem was that pip and python were linked to different versions.
The solution was to install via sudo /usr/bin/python3.8 -m pip uninstall numpy and then sudo /usr/bin/python3.8 install numpy
After looking into circular imports for a bit, it looks like you might just be better off doing import numpy and altering your code accordingly rather than using the from syntax
I am trying to install the Sklearn python library using
pip install sklearn
in cmd terminal in windows 8.
its shows no error. but when i am executing my code it gives error stating
Traceback (most recent call last):

i googled a lot.
This question is related to a question here: Unable to import numpy
I ran: sudo pip install --upgrade numpy
then when I ran python and tried to import numpy I got this strange error!!! I'm going crazy!

I also ran this:

The fix for me to was to manually install gcc via macports:
sudo port install gcc48
... which installs gfortran, but without the alias that numpy seems to be expecting (gfortran). Then we make a symlink:
sudo ln -s /opt/local/bin/gfortran-mp-4.8 /opt/local/bin/gfortran
After that, I uninstalled and reinstalled numpy via pip and it works like a charm.
This fixed the issue for me on mavericks last night. From what I've read, gfortran used to be part of the OS X command line tools, but isn't as of Lion or so. Installing gcc separately "fixes" that.
I tried to get atpy on python 2.7. I downloaded ATpy0.9.6 from
https://pypi.python.org/pypi/ATpy/0.9.6
then tar it, and run:
cd ATpy0.9.6
sudo python setup.py install
things seemed to work well.
But when I tried to import atpy on python, I got always this error message:
ImportError: No module named astropy.io
More precisely,
>>> import atpy
Traceback (most recent call last):

Could anyone help me to figure out the problem?
Perhaps the 'atpy' package depends on another package called 'astropy.io' that you are missing? Yes here it is https://astropy.readthedocs.org/en/v0.1/index.html
It happens that downloading the tar balls from pypi.python.org is the wrong way to install Python packages. The right way (though the Python docs explain poorly), is to run a command like
pip install atpy
This command will install your package and all its dependencies.
If the command pip is missing, you have to install it, which is ironically really complicated.
In my case the solution was to install astropy
pip install --no-deps astropy
I'm trying to install couchdb app on debian using the following command
couchapp push http://user:pass#localhost:5984/acra-appname
and I'm having the following error output:

from restkit import ResourceError

As far as I understand the error is:
ImportError: No module named socketpool
How can I install this module or how to resolve the problem?
As Ifthikhan sugessted: Install it using a package manager such as apt-get and thereafter using pip you can install socketpool.
I had this problem when installing couchapp. I used pip to install it, and I thought it completed, but when I ran it I had the ImportError problem. Turns out the pip install didn't succeed and I first needed to:
apt-get install python-dev
Then when I did a
pip install couchapp
all of the dependencies were installed and couchapp ran without a problem.
