Hi I have encountered such problem when loading the function install_tensorflow() in r.
I don't know what to do with this error. Any help will be greatly appreciated!
Below is the error message

I have been trying to get a Jupyter object detection tutorial to run but for some reason, when the left hand side should go from In[] and switch to In1, it stays as In[0]. I assume this means the code isn't actually running. The top of the page also says there is a Kernel Error and when I click this, the following code is displayed:

I am not sure why there is an import error. For reference, I have downloaded CUDA 10.1, cuDNN 7.6.5, anaconda for python 3.6, and TensorFlow 2.0.0. Please let me know how I can fix this to get the Jupyter code to run.
I had the same problem. Then I rebooted and it worked fine.
When I want to print any report I got this message : wkhtmltopdf failed (error code: -8). Message: b"
This problem only for Odoo 12 version but for the previous versions it work well ..
this link will show the warning message : Wkhtmltopdf warning
And this is the log :

Please help me ..
I found a solution for this problem.
Try this:
sudo apt install ttf-mscorefonts-installer
sudo fc-cache -f -v
The problem come from the fonts. In Odoo12, default font for Bootstrap 4 is Noto Color Emoji and because of that, when you generate a report, wkhtmltopdf will crash. After this package you will have this font.
If problem persist, try to install also - http://download.odoo.com/fonts/Roboto-Regular.ttf
Tell me if it works. You can track this issue right here - https://github.com/odoo/odoo/issues/27487

Jupyter 4.2.0 is pretty old, and is not compatible with Tornado versions newer than 5.0. You need to either upgrade to a newer version of Jupyter or downgrade to an older version of Tornado (with pip, this would be pip install "tornado<5.0". I don't know the conda equivalent)
