system: Linux 4.15.0-99-generic #100~16.04.1-Ubuntu x86_64 GNU/Linux
tensorflow-gpu v2.2.0 installed via pip
Python 3.7.4 (default, Aug 13 2019, 20:35:49) [GCC 7.3.0] :: Anaconda, Inc. on linux

Minimal example:

tf.python.framework.device_spec.DeviceSpecV2().from_string(tf.config.list_physical_devices()
[0].name)

Traceback (most recent call last):

@jaingaurav do you want to take this?

Hi,
I encountered the same issue. My workaround is to use tf.config.list_logical_devices() instead of tf.config.list_physical_devices() but I am not really satisfied.
Any news about this problem?
Thanks!

@philippeller Could you please try on latest stable version of tf 2.5 or 2.4.1 and let us know if this is still an issue.Thanks!

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you.

Hi, looks to me as this is still the same issue in tf 2.5:

>>> tf.DeviceSpec().from_string(tf.config.list_physical_devices()[0].name)                                                                                                                                                                    
raise ValueError("Unknown attribute: '%s' in '%s'" % (y[0], spec))
ValueError: Unknown attribute: 'physical_device' in '/physical_device:CPU:0'
>>> tf.__version__
'2.5.0'

This issue still persists on the latest TF V2.12 and Tf-nightly. Please find the gist of 2.12 and tf-nightly for reference .
Thank you!
