Hi,
I am a little confused as I have exactely the same issue then the last solved one previously (please see this link (No Space Left on Device for qiime feature-classifier ) with the feature classifier. i changed the tmp directory with TEMPDIR=/some/directory but I still have have the same problème.
Any suggestion on how you solved this problème will be appreciated
Thanks
Hi @biotama - what command are you running to change your temporary directory? The snippet you provided above has a minor typo, the environment variable name is TMPDIR, not TEMPDIR, so that is probably what is going on here. If tweaking the variable name like I suggest here doesn’t help, please provide all of the commands you are running, including your feature classifier command, and the command for setting the environment variable. Thanks! 
Hi, oh sorry for the mistake in the command, here is the commands i run:
ls /data
skynet@skynet-HP-Z640-Workstation:~$ export TMPDIR=/data
skynet@skynet-HP-Z640-Workstation:~$ echo $TMPDIR
/data
skynet@skynet-HP-Z640-Workstation:~$ source activate qiime2-2017.12
(qiime2-2017.12) skynet@skynet-HP-Z640-Workstation:~$ cd qiime2-final
(qiime2-2017.12) skynet@skynet-HP-Z640-Workstation:~/qiime2-final$ qiime feature-classifier classify-sklearn --i-classifier silva-119-99-515-806-nb-classifier.qza --i-reads rep-seqs.qza --o-classification taxonomy.qza
I just wanted to add that in my case this issue happened only on linux machine, I tried to run the command on Mac OS and it seems Work but it take all the memory (I have just 4go) leading to a big bug, so I can’t do anything…
Thanks
Is this environment activation resetting your TMPDIR variable? What does echo $TMPDIR return after you activate your conda env?
It returns the same place /data after or before activating conda env
Thx
Well, it sounds like you are running out of disk space 
What does df -h have to tell you about the /data path? If that isn’t a separate mount it will be listed under the “mounted on” entry for /.
Can you also please provide the exact error you are receiving? Copy and paste please. Thanks!
I don’t know if this correct… I run the df -h and it returns this list below
skynet@skynet-HP-Z640-Workstation:/data$ df -h

My apologies for taking you busy with this…
No worries @biotama!
Thanks for all the extra info, that was super useful! So, looking at your df results, you only have 3.5G of space available for /data, it is entirely possible that you are fully exhausting that tiny bit of space when running feature-classifier.
It does look like your home directory has plenty of space (155G free), how about setting TMPDIR to /home/skynet/tmp? You would need to make that directory first, and of course you could stash that somewhere else more appropriate to your home directory layout. Please give that a shot and let us know how it goes!
Hi, now it works!!! thanks thermokarst! it takes one CPU, is there any option to add more than one?
Thanks
