AttributeError: 'module' object has no attribute 'database_test'

[benzben]

After hours of installing dependencies so that the install.sh will finish without errors, the setup.py test returns the error "AttributeError: 'module' object has no attribute 'database_test'". Testing for the database by using

python |>>> import test.database_test

Returns: Traceback (most recent call last): File "", line 1, in File "test/database_test.py", line 27, in import IPython ImportError: No module named IPython

But I installed iPython, 5.1.0.

What's wrong with my installation? I would be glad for some help :-)

[jeffmahler]

There is a probably some discrepancy between the Python and ipython installation. This seems to be relevant.

Can you paste the output of:

which python
which ipython

[benzben]

@jeffmahler Thanks for your answer. I will have a look at your link, however, the output of these commands return: /usr/bin/python and /usr/local/bin/ipython

Do they have to be located in the same path?

I am module object has no attribute 'database_test' after installing Dex Net 2.0 , Please help.

[jeffmahler]

Please see above discussion. Can you paste the output of the following?:

python
|>>> import test.database_test

[kundan09]

@jeffmahler I exceuted the code in dexnet directory .i.e home/robo/catkin_ws/src/dexnet python test/database_test.py and

i got an error as core dumped, i am installing it on CPU machine. Is the installtion tested on CPU system.

@jeffmahler

Output of import test.database_test

Please look into the issue and suggest me the required changes to do.

[jeffmahler]

@kundan09 I actually think your tests completed successfully! The error Floating point exception (core dumped) seems to happen on some machines during script termination and is related to matplotlib. I was never able to figure that out, but if it only happens on termination then you're ok.

[kundan09]

@jeffmahler Is the installtion tested on CPU system ?

Hi @jeffmahler,

I am using Ubuntu 16.04 and I am facing a very similar issue. I followed all the steps listed here https://docs.google.com/document/d/1YImq1cBTy9E1n1On6-00gueDT4hfmYJK4uOcxZIzPoY/edit to install dex-net. So far everything works fine. Unfortunately when I am running sudo python setup.py test I have the following log

running test running egg_info writing requirements to src/dex_net.egg-info/requires.txt writing src/dex_net.egg-info/PKG-INFO writing top-level names to src/dex_net.egg-info/top_level.txt writing dependency_links to src/dex_net.egg-info/dependency_links.txt reading manifest file 'src/dex_net.egg-info/SOURCES.txt' writing manifest file 'src/dex_net.egg-info/SOURCES.txt' running build_ext Traceback (most recent call last): File "setup.py", line 42, in test_suite='test' File "/usr/local/lib/python2.7/dist-packages/setuptools/init.py", line 145, in setup return distutils.core.setup(**attrs) File "/usr/lib/python2.7/distutils/core.py", line 151, in setup dist.run_commands() File "/usr/lib/python2.7/distutils/dist.py", line 953, in run_commands self.run_command(cmd) File "/usr/lib/python2.7/distutils/dist.py", line 972, in run_command cmd_obj.run() File "/usr/local/lib/python2.7/dist-packages/setuptools/command/test.py", line 228, in run self.run_tests() File "/usr/local/lib/python2.7/dist-packages/setuptools/command/test.py", line 250, in run_tests exit=False, File "/usr/lib/python2.7/unittest/main.py", line 94, in init self.parseArgs(argv) File "/usr/lib/python2.7/unittest/main.py", line 149, in parseArgs self.createTests() File "/usr/lib/python2.7/unittest/main.py", line 158, in createTests self.module) File "/usr/lib/python2.7/unittest/loader.py", line 130, in loadTestsFromNames suites = [self.loadTestsFromName(name, module) for name in names] File "/usr/lib/python2.7/unittest/loader.py", line 103, in loadTestsFromName return self.loadTestsFromModule(obj) File "/usr/local/lib/python2.7/dist-packages/setuptools/command/test.py", line 54, in loadTestsFromModule tests.append(self.loadTestsFromName(submodule)) File "/usr/lib/python2.7/unittest/loader.py", line 100, in loadTestsFromName parent, obj = obj, getattr(obj, part) AttributeError: 'module' object has no attribute 'database_test'

Reading all the issues carefully, in dex-net folder I run python and then >> import test.database_test and here is the output

I have spent the last days trying to install dex-net on different machines and always the same issue. Any clues?

Thanks

[jeffmahler]

You are missing a dependency required to run the tests. Did you install the dependencies using sudo? That may be causing issues. I highly recommend using a virtualenv and installing all dependencies locally

[bdenoun]

Thank you for your quick reply. Yes I used sudo as specified in the aforementioned document. Let me try going through all the process without using it and come back to you

[bdenoun]

@jeffmahler So I ran all the same steps except for installing 3rd party dependencies (I had to add --user to the pip instruction in the bash file). Here is the output of python setup.py test

Ran 15 tests in 83.398s

OK Floating point exception (core dumped)

It seems like a lot of tests are OK but it still have this warnings about mayavi, dexnet.api, trimesh and so on (same as before). The weird thing this time is that it doesn't recognize tensorflow but I guess this is another story. Should I worry about those warnings or should I consider the test successful?

Thank you

[jeffmahler]

It looks like the tests passed! You may have problems with visualization due to the failed mayavi import. I would try to re-install it. It's possible that this is related to your computer hardware.

[bdenoun]

Through a pip install or the build?

[jeffmahler]

It is supposed to be installed through pip. I believe that you are probably encountering errors in that process. Unfortunately I can't support mayavi install issues though.

[bdenoun]

Thank you very much for your help! Yes I did using pip and still the same issue but it can be from mayavi (though import mayavi works fine). Can I suggest to maybe modify the linked document with installation instructions so that people don't face the same issue?

[jeffmahler]

Yes, can you add comments / suggestions for your issues to the installation doc?
