1.run the demo of Ianvs Execution and Presentation in your own cluster

Note:

1. Demo is using the Linux platform with Python 3.6.9. That means you can`t run it in Ubuntu22.04(at least I cany`t and ppa tell me that for jammy, older python versions requre libssl<3 so they are not currently built).I run it on Ubuntu20.4 with 3.6.15. And you must install python3.6-dev and gcc to install pycocotools with pip.
2. I cant`t install PyYAML due to 5.3. installed , and I use python3.6 -m pip install ./examples/resources/third_party/* --ignore-installed to solve it.
