Qiime2-2017.8 installation: segmentation fault

nir · September 19, 2017, 3:25pm

hi,
i installed qiime2 on a scientific linux server (with some problems relating to having a python alias and PYTHONPATH, remanents from the qiime 1.8 install).
now after activating the env, when i enter “qiime --help” i get
"QIIME is caching your current deployment for improved performance. This may take a few moments and should only happen once per deployment."
and soon afterwards:
"Segmentation fault"
ideas?
thanks.

Hi @nir! What are the exact commands you ran to install QIIME 2? Are you on a 64-bit Linux system?

nir · September 20, 2017, 4:49pm

hi,
yes, it’s a 64 bit linx system.
i installed using conda with python3.5. after an unsuccesful install i did:

conda env remove -n qiime2-2017.8
conda clean -y --all
conda create -n qiime2-2017.8 --file https://data.qiime2.org/distro/core/qiime2-2017.8-conda-linux-64.txt

installation finished ok, but after
source activate qiime2-2017.8
qiime --help

i get:
QIIME is caching your current deployment for improved performance. This may take a few moments and should only happen once per deployment.
and shortly after:
Segmentation fault

two potential problems come to mind: i don’t have root access, just a user.
something is clashing with older qiime version (1.8) or dependencies

Thanks for the details @nir! Those commands all look good.

One quick thing to try: remove your qiime2-2017.8 environment, run conda clean -y --all, and then run conda update conda. After that try reinstalling qiime2. If that works, great! If not, let's continue debugging (see instructions below).

It doesn't seem like a permissions issue since you're able to create, remove, and activate environments without elevated permissions.

This sounds very likely. I'll need to gather some more details to help debug this. Can you open a new terminal window, run the following commands, and send me the output?

uname -a
alias python
echo $PYTHONPATH
tree $HOME/.local/lib
conda info -a

Additionally, please run the following commands, first without activating your qiime2-2017.8 environment, and then after activating your qiime2 environment:

which python
python --version
which qiime
conda list
python -c "import numpy; print(numpy.__version__)"

Thanks!

hi,
during installation i got:

dbus post-link :: /etc/machine-id not found ..

is it ok?

Thanks for sharing the output from those commands! Nothing looks suspicious here, there doesn’t appear to be a conflicting install or pythonpath issues. Well that’s good news!

Just to double-check something, can you run this command and send me the output?

ls -la $HOME/.local/lib

Let’s also use gdb (a debugging tool) to find out more about the segmentation fault you’re running into:

Check if you have gdb installed by simply running gdb. If you receive an error stating “no such command”, you’ll need to install gdb. There’s instructions here, you may need your system administrator to install it for you depending on your user permissions.
Once you have gdb installed, run:
```
gdb -ex r --args python -c "import qiime2.sdk; qiime2.sdk.PluginManager();"
```
This should hopefully reproduce the segfault and drop you into a gdb debugger session.
From within the gdb interactive shell, run:
```
bt
py-bt
```
Run the quit command to exit the gdb session.

Please send me all output from Steps 2 and 3 above. Thanks for bearing with me on debugging this!

py-bt doesn't work. it says:

(gdb) py-bt
Undefined command: "py-bt". Try "help".

thanks for all your help

Hi @nir, sorry for the slow reply! Thanks for the debug info, this is really helpful. It looks like either the sip or PyQt5 packages are causing the segfault. matplotlib is a QIIME 2 dependency that uses both of those packages, so let’s try importing those packages individually to see if we can reproduce the segfault.

Can you send me the output from these commands?

python -c "import matplotlib"
python -c "import sip"
python -c "import PyQt5"

Can you also send me the output from this command? It’ll show what matplotlib backend is being used, which I suspect is a Qt backend.

cat $(python -c "import matplotlib; print(matplotlib.matplotlib_fname())") | grep -i backend

Thanks, I think we’re narrowing in here!

hi,
the three libraries imported without output.

last command output:

(qiime2-2017.8) [werbnen@master ~] cat (python -c "import matplotlib; print(matplotlib.matplotlib_fname())") | grep -i backend
#The default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo
#You can also deploy your own backend outside of matplotlib by
#'module://my_backend'.
backend : Qt5Agg
#If you are using the Qt4Agg backend, you can choose here
backend.qt4 : PyQt4 # PyQt4 | PySide
#The port to use for the web server in the WebAgg backend.
#When True, the figures rendered in the nbagg backend are created with
#if you are running pyplot inside a GUI and your backend choice
#you if backend_fallback is True
#backend_fallback: True
# This only affects the Agg backend.
# backends but will workd with temporary file based ones:
#tk backend params
#ps backend params
#pdf backend params
#svg backend params
#animation.writer : ffmpeg # MovieWriter 'backend' to use

ok, nailed it:

(qiime2-2017.8) [werbnen@master ~]$ python -c "import PyQt5.QtCore"
Segmentation fault

nir · October 1, 2017, 5:25am

after uninstalling and reinstalling with pip, i get:

(qiime2-2017.8) [werbnen@master ~]$ python -c "import PyQt5.QtCore"
Traceback (most recent call last):
File "", line 1, in

nir · October 1, 2017, 8:19am

ok, so i uninstalled and reinstalled PyQt5 sip and matplotlib, and now installed matplotlib with --no-cache-dir.
i think it works! at least it finished the caching phase.
thanks a lot!

jairideout · October 2, 2017, 9:59pm

Hi @nir, that’s awesome that you found a workaround! It looks like the issue is due to the default matplotlib rendering backend that ships with your platform (Qt5Agg). Fortunately QIIME 2 doesn’t require this backend so we can swap it out for something else.

We just released QIIME 2 2017.9 last week and fixed this matplotlib backend issue. Can you try installing 2017.9 following the install docs? That’ll provide you with a clean 2017.9 install that should “just work”.

Another benefit to upgrading to 2017.9: we only provide support for the latest QIIME 2 release, so we won’t be providing support for 2017.8 much longer. Let me know how it goes!
