nosetests regreg ERROR

[xizepu]

Dear, My environment:

Mac OS 10.12.3
Python 2.7
Anaconda2
cython 0.25.2

and after I build and install regreg, I do nosetests regreg and there have 27 errors. the error messages are:

ERROR: Failure: ImportError (No module named projl1_cython)
Traceback (most recent call last):

How to solve this problem? Many thanks!

How did you build and install regreg?
Is it possible you are running the tests from the regreg directory? If so, try running the tests from another directory, such as your home directory.

Dear Prof. Matthew, Many Thanks.
Firstly, I

git clone git://github.com/regreg/regreg.git

and enter regreg directory, and then

sudo python setup.py build

and in this process, there have some warnings, such as:

warning: "Using
deprecated NumPy API, disable it by " "#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-W#warnings]
#warning "Using deprecated NumPy API, disable it by "
^
1 warning generated.

and I ignore this warning, and run

sudo python setup.py install

the output message are:

Using /Users/xizepu/anaconda2/lib/python2.7/site-packages
Finished processing dependencies for regreg==0+untagged.840.gef5533d

There are screenshot

and then I start do 'nosetests regreg'. I do two ways for this step. The first step is same as my first post, I run test at $my_home/regreg and run:

nosetests regreg

the error message show FAILED (errors=27),

and I now running the tests from another directory, such as my home directory(I use zsh):

➜ ~ pwd
/Users/xizepu

There also have 27 errors

I run tests in /Users/xizepu/regreg/regreg, and also have 27 errors.

And the main error is:

File "/Users/xizepu/regreg/regreg/atoms/seminorms.py", line 13, in
from .projl1_cython import projl1
ImportError: No module named projl1_cython

That say in $myhome/regreg/atoms/seminorms.py file, when do from .projl1_cython import proj1.

I open seminorm.py and screenshot in HERE

and open projl1_cython.pyx in directory My_Home/regreg/regreg/atoms/:

Like this

the projl1_cython.pyx

and this

Dear Prof. so many thanks for YOU!

[matthew-brett]

So - I'd recommend you do the following:

• remove your current installation of regreg:

cd  # cd to you your home directory
python -c 'import regreg; print(regreg.__file__)'

Delete the directory that gets printed out.

Now reinstall with pip

cd ~/regreg
git clean -fxd
pip install --user .

Then:

cd # back to your home directory
nosetests regreg

Could you post the output from that last command?

[xizepu]

Many Thanks!

I removed the current installation of regreg.and reinstall with your tips.

I run pip install --user . at ~/regreg, the message are:

➜ regreg git:(master) pip install --user .

package regreg is installed at ~/.local/lib/python2.7/site-packages/, like

➜ site-packages pwd

➜ site-packages tree -d

11 directories

Then I cd to my home directory, and run nosetests regreg, there also have 27 errors. the error message is:

ERROR: Failure: ImportError (No module named projl1_cython)

Ran 30 tests in 0.394s
FAILED (errors=27)

Any way, this message point the error in from .projl1_cython import projl1, but when I import this in manual, NO REEOES :(
like this screenshot

by the way, when I run nosetests numpy there also have error, and nosetest pip it show OK.

Many thanks!

[matthew-brett]

I notice that nose is still picking up the source directory of regreg:

mod = load_module(part_fqname, fh, filename, desc)
File "/Users/xizepu/regreg/regreg/tests/test_path.py", line 1, in 
import numpy as np, regreg.api as rr

I'm not sure how to explain that - but that's the reason that the tests are failing - it's trying to run the tests from the source directory.

[xizepu]

Many thanks for you! Let me try in another way. Many thanks!

[matthew-brett]

Ah - I see the problem - nosetests is interpreting regreg as a directory, and so running the tests on the source directory. Try:

mkdir tmp
cd tmp
nosetests regreg

I guess that will work.

[jonathan-taylor]

I guess having source under regreg is sort of non-standard. Could be moved I supposed.
