Install Anaconda, CUDA, etc.
Create new virtual environment with python version 3.6 (mainly due to PyTorch) and activate it:

Now git clone the udacity repo and install dependencies:

git clone
cd deep-reinforcement-learning/python

Before install, at the currently moment need to comment out the torch installation by removing line “torch==0.4.0”…

8K video shoot on mobile phone, the simple tests on Note 20 Ultra

From my simple point of view, the 8K shooting on Note 20 Ultra is probably more like a commercial gimmick or something you could show off on your phone rather to have some real practical use. It might be useful if you apply a gimble (eg osmo mobile) to stabilise the footage as while shooting in 8K, the stabilisation is really very basic and limited. Also the Zooming, tracking auto-focus and some other stuff are not available in the 8K, either, make the 4K more practical to produce something useful (this is also considering that 8K video is not very widely watched for now). No mention the 24 fps Vs. 60 fps, that limit some of your post-editing space.
