Flame's animation curve interpolation code from Julik Tarkhanov: https://github.com/guerilla-di/flame_channel_parser
- Download latest release from Releases page
- All you need to do is put the .py file in /opt/Autodesk/shared/python and launch/relaunch flame. The first time it will upack/install what it needs. It will give you a prompt to let you know when it’s finished.
- It is possible to choose the installation folder. Default installation folders are:
~/Documents/flameTimewarpML # Mac
~/flameTimewarpML # Linux
- In case you'd need to reset preferences
~/Library/Preferences/flameTimewarpML # Mac
~/.config/flameTimewarpML # Linux
- There are an option to set working folder over env variable
Setting FLAMETWML_DEFAULT_WORK_FOLDER will set default folder and user will still be allowed to change it
export FLAMETWML_DEFAULT_WORK_FOLDER=/Volumes/projects/my_timewarps/
- Setting FLAMETWML_WORK_FOLDER will block user from changing it. This read every time just before the tool is launched so one can use it with other pipeline tools to change it dynamically depending on context
export FLAMETWML_WORK_FOLDER=/Volumes/projects/my_timewarps/
- Setting FLAMETWML_HARDCOMMIT will lead to imported clip hard commited after import and all temporary files deleted
export FLAMETWML_HARDCOMMIT=True
-
It is possible to do easy install on one of the workstations to common location and then configure other via env variables (see Centralised configuration section)
-
flameTimewarpML is made of three components.
1) Miniconda3 isolated Python 3.8 environment with some additional dependence libraries (see requiremens.txt)
2) A set of python scripts that are called from command line and should be running within Python 3.8 environment. Those two parts are not dependant on Flame and can be run as a standalone tools.
3) Flame script to be run inside Flame. It has to know the location of two previous parts to be able to initialize Python 3.8 environment and then run command line tools to process image sequences. -
Get the source from Releases page or directly from repo:
git clone https://github.com/talosh/flameTimewarpML.git
- It is possible to share Python3 code location between platforms, but Miniconda3 python environment should be placed separately for Mac and Linux. This exmaple will use:
Python3 code location:
/Volumes/software/flameTimewarpML # Mac
/mnt/software/flameTimewarpML # Linux
miniconda3 location:
/Volumes/software/miniconda3 # Mac
/mnt/software/miniconda3 # Linux
-
Do not place those folders inside Flame's python hooks folder. The only file that should be placed in Flame hooks folder is flameTimewarpML.py
-
Create folders
mkdir -p /Volumes/software/flameTimewarpML # Mac
mkdir -p /Volumes/software/miniconda3 # Mac
mkdir -p /mnt/software/flameTimewarpML # Linux
mkdir -p /mnt/software/miniconda3 # Linux
- Copy the contents of 'bundle' folder to the code location.
cp -a bundle/* /Volumes/software/flameTimewarpML/ # Mac
cp -a bundle/* /mnt/software/flameTimewarpML/ # Linux
-
Download Miniconda3 for Python 3.8 from https://docs.conda.io/en/latest/miniconda.html
Shell installer is used for this example. -
Install Miniconda3 to centralized location:
sh Miniconda3-latest-MacOSX-x86_64.sh -bu -p /Volumes/software/miniconda3/ # Mac
sh Miniconda3-latest-Linux-x86_64.sh -bu -p /mnt/software/miniconda3/ # Linux
-
In case you'd like to move Miniconda3 installation later you'll have to re-install it again. Please refer to Anaconda docs: https://docs.anaconda.com/anaconda/user-guide/tasks/move-directory/
-
Init installed Miniconda3 environment:
/Volumes/software/flameTimewarpML/init_env /Volumes/software/miniconda3/ # Mac
/mnt/software/flameTimewarpML/init_env /mnt/software/miniconda3/ # Linux
The script will open new konsole window.
- In case you do it over ssh remotely on Linux edit the line at the very end of init_env
cmd_prefix = 'konsole -e /bin/bash --rcfile ' + tmp_bash_rc_file
cmd_prefix = '/bin/bash --rcfile ' + tmp_bash_rc_file
-
To check if environment is properly initialized: there should be (base) before shell prompt. python --version should give Python 3.8.5 or greater
-
From this shell prompt install dependency libraries:
pip3 install -r /Volumes/software/flameTimewarpML/requirements.txt # Mac
pip3 install -r /mnt/software/flameTimewarpML/requirements.txt # Linux
- It is possible to download the packages and install it without internet connection. Install Miniconda3 on the machine that is connected to internet and download dependency packages:
pip3 download -r bundle/requirements.txt -d packages_folder
then it is possible to install packages from folder:
pip3 install -r /Volumes/software/flameTimewarpML/requirements.txt --no-index --find-links /Volumes/software/flameTimewarpML/packages_folder
-
Copy flameTimewarpML.py to your Flame python scripts folder
-
set FLAMETWML_BUNDLE, FLAMETWML_MINICONDA environment variables to point code and miniconda locations.
export FLAMETWML_BUNDLE=/Volumes/software/flameTimewarpML/ # Mac
export FLAMETWML_MINICONDA=//Volumes/software/miniconda3/ # Mac
export FLAMETWML_BUNDLE=/mnt/software/flameTimewarpML/ # Linux
export FLAMETWML_MINICONDA=/mnt/software/miniconda3/ # Linux
More granular settings per platform possible with
export FLAMETWML_BUNDLE_MAC=/Volumes/software/flameTimewarpML/
export FLAMETWML_BUNDLE_LINUX=/mnt/software/flameTimewarpML/
export FLAMETWML_MINICONDA_MAC=/Volumes/software/miniconda3/
export FLAMETWML_MINICONDA_LINUX=mnt/software/miniconda3/
