Octoprint: AttributeError: 'module' object has no attribute 'cpu_freq'

[hpoleselo]

Hello, i'm trying to run Octoprint on Ubuntu 16.04 and installed supposedly correctly, i.e using Python 2.7.
After following all the steps to install Octoprint on my machine, i tried to run Octoprint with the following command:
$ octoprint serve

And the result is:

/usr/local/lib/python2.7/dist-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.25.3) or chardet (2.3.0) doesn't match a supported version!
  RequestsDependencyWarning)

Hi @hpoleselo,

It looks like there is some information missing from your bug report that will be needed in order to solve the problem. Read the Contribution Guidelines which will provide you with a template to fill out here so that your bug report is ready to be investigated (I promise I'll go away then too!).

If you did not intend to report a bug but wanted to request a feature or brain storm about some kind of development, please take special note of the title format to use as described in the Contribution Guidelines.

Please do not abuse the bug tracker as a support forum - that can be found at discourse.octoprint.org. Go there for any kind of issues with network connectivity, webcam functionality, printer detection or any other kind of such support requests or general questions.

Also make sure you are at the right place - this is the bug tracker of the official version of OctoPrint, not the Raspberry Pi image OctoPi nor any unbundled third party OctoPrint plugins or unofficial versions. Make sure too that you have read through the Frequently Asked Questions and searched the existing tickets for your problem - try multiple search terms please.

I'm marking this one now as needing some more information. Please understand that if you do not provide that information within the next two weeks (until 2019-06-10 16:10 UTC) I'll close this ticket so it doesn't clutter the bug tracker. This is nothing personal, so please just be considerate and help the maintainers solve this problem quickly by following the guidelines linked above. Remember, the less time the devs have to spend running after information on tickets, the more time they have to actually solve problems and add awesome new features. Thank you!

Best regards,
~ Your friendly GitIssueBot

PS: I'm just an automated script, not a human being, so don't expect any replies from me :) Your ticket is read by humans too, I'm just not one of them.

It's hard to read the log because it's all jammed together, rather than each line starting properly. Can you reformat? Also, the cpu_freq exception is properly caught and handled; the actual error is at the end, and it is cut off (truncated).

[hpoleselo]

So i realized there was an older version from tornado (4.2.2) and it was somehow implicitly conflicting with the one which was trying to be installed...
So i just:

$ sudo rm -rf /usr/local/lib/python2.7/dist-packages/tornado
$ sudo rm -rf /usr/lib/python2.7/dist-packages/tornado

And then:
$ sudo pip2.7 install . --ignore-installed ${tornado}

[foosel]

And why did you decide to not follow the official install instructions, which explicitly tell you to install into a virtual environment instead of doing a global install, to avoid version conflicts like this among other things? ;)

[hpoleselo]

In my case i'm trying to integrate OctoPrint with ROS and creating the virtual environment was not possible, but thanks for the heads up!
