ItsMichal

So, IKPY is surprisingly not as robust a library as I would have imagined, and its quite poorly documented. After struggling for a few days trying to get it to work with TIAGO Steel, here are some things that helped.

• So, IKPY is actually a bit outdated. Optionally, I'd recommend installing a fork of IKPY by user Alters-Mit which fixes some issues with prismatic joints, which the TIAGO Steel contains. More info here. Phylliade/ikpy#96
  • To install this fork of ikpy, run pip install git+https://github.com/alters-mit/ikpy.git#egg=ikpy in your console.
  • I'm not sure if this helped, but it seemed to. If you don't have problems, do this optionally.
  • Finally, put the following at the top of your controller file-

  • from ikpy.chain import Chain
    from ikpy.link import OriginLink, URDFLink

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of

I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com.

example: The following JSON document:  
{"maps":[{"id1":"blabla","iscategorical1":"0", "perro":[{"dog1": "1", "dog2": "2"}]},{"id2":"blabla","iscategorical2":"0"}],
"masks":{"id":"valore"},
"om_points":"value",
"parameters":{"id":"valore"}}

will have the following output:
{'masks.id': 'valore', 'maps.iscategorical2': '0', 'om_points': 'value', 'maps.iscategorical1': '0', 
'maps.id1': 'blabla', 'parameters.id': 'valore', 'maps.perro.dog2': '2', 'maps.perro.dog1': '1', 'maps.id2': 'blabla'}
