[SOLVED] python-tensorflow and python-tensorflow-cuda: Error Message

I am using both the python-tensorflow and python-tensorflow-cuda packages (on two different machines). After upgrading the packages from version 1.1.0-4 to 1.2.0-1 I am receiving the error message below.

Traceback (most recent call last):
  File "/usr/bin/tensorboard", line 7, in <module>
    from tensorflow.tensorboard.tensorboard import main
  File "/usr/lib/python3.6/site-packages/tensorflow/__init__.py", line 24, in <module>

    from backports import weakref  # pylint: disable=g-bad-import-order
ModuleNotFoundError: No module named 'backports'

Are these packages broken after the update or am I doing something wrong here?

Re: [SOLVED] python-tensorflow and python-tensorflow-cuda: Error Message

A bit of googling led me to this:  https://bugs.archlinux.org/task/54606

So I would try the fix thats listed there and see if it works for you

" To make it work, need to replace
from backports import weakref
on line 28 of "/usr/lib/python3.6/site-packages/tensorflow/python/util/tf_should_use.py" with
import weakref "

Re: [SOLVED] python-tensorflow and python-tensorflow-cuda: Error Message

Thank you, sir. This fix seems to solve the problem for me. I was looking into this issue yesterday, but this bug report was submitted only today, so that's probably why I didn't come across it myself. Additionally, I was getting errors when trying to run tensorboard:

$ tensorboard --logdir=./logs

Traceback (most recent call last):
  File "/usr/bin/tensorboard", line 7, in <module>
    from tensorflow.tensorboard.tensorboard import main
  File "/usr/lib/python3.6/site-packages/tensorflow/tensorboard/tensorboard.py", line 28, in <module>
    from werkzeug import serving
ModuleNotFoundError: No module named 'werkzeug'

Traceback (most recent call last):
  File "/usr/bin/tensorboard", line 7, in <module>
    from tensorflow.tensorboard.tensorboard import main
  File "/usr/lib/python3.6/site-packages/tensorflow/tensorboard/tensorboard.py", line 36, in <module>
    from tensorflow.tensorboard.plugins.text import text_plugin
  File "/usr/lib/python3.6/site-packages/tensorflow/tensorboard/plugins/text/text_plugin.py", line 29, in <module>
    import bleach
ModuleNotFoundError: No module named 'bleach'

Traceback (most recent call last):
  File "/usr/bin/tensorboard", line 7, in <module>
    from tensorflow.tensorboard.tensorboard import main
  File "/usr/lib/python3.6/site-packages/tensorflow/tensorboard/tensorboard.py", line 36, in <module>
    from tensorflow.tensorboard.plugins.text import text_plugin
  File "/usr/lib/python3.6/site-packages/tensorflow/tensorboard/plugins/text/text_plugin.py", line 32, in <module>
    import markdown
ModuleNotFoundError: No module named 'markdown'

I was able to resolve these issues by explicitly installing the corresponding packages from the official repositories as follows:

# pacman -S python-werkzeug python-bleach python-markdown

I suspect these packages are missing dependencies and I will open a bug report myself.
