#26474we need to relax the typing and sharding rule checks because if we insertmesh_casts, those lead to creation of unnecessary residuals (for literals, numpy arrays, basically anything that has an empty mesh) which is not good.
不幸的是，在MacOS 10.13（只有10.14或11）的Python包索引（https://PyPi.org）上没有PyArrow 12.0.1的预构建版本，因此pip试图从源代码构建PyArrow，这需要比安装预构建版本更多的设置。但是，PyPi上有一些预构建的版本，适用于较旧的PyArrow版本，如9.0.0。由于Streamlit只需要PyArrow版本4.0.0或更高版本，...

In the beginning of the learning, the agent has an empty memory and also does not know yet what actions to take. We can assume, that a random policy would do the same job in choosing actions, but at much higher rate. Therefore we can simply fill the memory of the agent before the ...
After some digging, it turned out that I usenp.emptyto create an array for action qualities. np.emptyis a fancy way of doingnp.zerosthat allocates memory but doesn’t initialize the NumPy array just yet. Because of that, from time to time some actions had updated scores (which overrode...
