Please run unit tests with this command:

python ./scripts/run_nupic_tests.py -u

Is the output the same? Also be sure to pull tip of master because we have made changes recently.

I am having the same issue when running the "py.test tests/unit" command, and when I run

python ./scripts/run_nupic_tests.py -u

I see the following:

python ./scripts/run_nupic_tests.py -u Traceback (most recent call last): File "./scripts/run_nupic_tests.py", line 262, in os.chdir(os.getenv('NUPIC')) TypeError: coercing to Unicode: need string or buffer, NoneType found

Hi LunaAmour,

I was having the same issue. I solved it by uninstalling nupic and using the --user option for installation.

Let me know if this is of any help.

[DeepakVellampalli]

Hello guys! Even I faced the same error while running "py.test tests/unit". As per your suggestion @ilialexander I reinstalled Nupic using "--user" option. After that "python ./scripts/run_nupic_tests.py -u" neither gave an error nor gave any type of output. Should I assume that everything got fixed? However, "py.test tests/unit" still gives the same error.

P.S : This solution of using "--user" installs the package globally and deprives the benefit of using virtual environment.

@DeepakVellampalli @rvsandeep Are you guys using virtualenv? Like @DeepakVellampalli said, you should not have to use --user with virtualenv

[Thanh-Binh]

@rhyolight I have the same issues with my Ubuntu, which can ONLY solved by using --user. I have no idea why it works sometimes by using --user, sometimes nur by using sudo?

[rvsandeep]

@rhyolight No i'm not using virtualenv. I tried the same steps on my mac as well and it's failing for the above tests as well.
713 passed, 17 skipped, 8 xfailed, 5 pytest-warnings in 210.08 seconds Update I tried using virtualenv and it completed with above message as well. On checking the test that was failing tests/unit/nupic/docs/examples_test.py . There were 8 tests (above failed ones) annoted as expected failure. So is this result expected out of run_test and I'm good to move on or am i missing something here?

[DeepakVellampalli]

@rhyolight I tried using virtualenv but it didn't work, so ended up installing by --user way.

[rhyolight]

You may have the wrong nupic.bindings version. Can you run pip list | grep nupic to find out? If you have anything less than 1.0.6 you should uninstall completely then run pip install nupic again. (thanks @lscheinkman for pointing this out)

[DeepakVellampalli]

@rhyolight You are right, I am having nupic.bindings 1.0.4. I think re-installation will work. Thank you so much!
