Can't find '/sys/class/hwmon/hwmon1/device/name'

[DariaD]

Good morning,

I was using an utility which refer to psutil and suddenly got:
IOError: [Errno 2] No such file or directory: '/sys/class/hwmon/hwmon1/device/name'

I'm not sure what exactly going on and if it's really a psutil problem.
Really appreciate any help!

>>> import psutil
>>> psutil.sensors_temperatures()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.7/site-packages/psutil/__init__.py", line 2195, in sensors_temperatures
    rawdict = _psplatform.sensors_temperatures()
  File "/usr/lib64/python2.7/site-packages/psutil/_pslinux.py", line 1154, in sensors_temperatures
    binary=False)

    return open(fname, "rt", **kwargs)
IOError: [Errno 2] No such file or directory: '/sys/class/hwmon/hwmon1/device/name'

I use Python 2 if it's mater.

Also, I use CentOS.

Can you please paste the output of sensors command? Not sure about CentOS but on Ubuntu you install it with sudo apt install lm-sensors.

[giampaolo]

Can you please try to install latest GIT version of psutil and then run this script and paste the output?

P.S. for CentOS:

$ yum install lm_sensors
