Python_OSError: [Errno 28] No space left on device

Question

I have the following error while exporting pandas dataframe into csv file. I have enough space on my hard disk.

OSError: [Errno 28] No space left on device

What can be the reason for this? Many thanks in advance.

Answer 1

I was using pipenv to install package.
I didn't have enough space in /tmp folder in linux, so solution was to temporary set another folder in TMPDIR env variable.

export TMPDIR=/path/to/directory/with/lot/of/space

More info about TMPDIR: docs.python

Answer 2

Late answer, but maybe usefull.

I encountered a similar issue :

OSError: [Errno 28] No space left on device:

But, I have enough space:

$ df -h

/dev/dm-0                   5,6G    3,2G  2,1G  62% /

data                         20G     11G  8,6G  56% /data

In fact, it's not a weight problem, it is an amount problem.

The evidence:

$ df -hi

data                        1,3M   1,3M      0  100% /data

There is no more place for inodes (files).

And this is clearly due to the session management:

$ du --max-depth=1 --inodes -h /data/my-python-program/data/
1,2M    /data/base-eelv/data/sessions
178 /data/base-eelv/data/medias

The quick fix is to empty the session directory.

The clean fix is to auto-cleanup, but at this time, I have'nt search how to do this.
