请问第四行命令有什么用

请问在hw3中使用的bin公式 bin = (lum[i] - lumMin) / lumRange * numBins 是否有问题。根据这个公式算出来的bin的数量其实为numBins+1，不知道如何处理比较好

I guess

When I run the cell # make the cuda project of the colab notebook udacity-cs344-hw1 I faced such an error as below. Could you help me?

Hi, I'm curious about how you manage to install the opencv requirements before compiling the code. Since I only see these before compilation

!git clone https://github.com/depctg/udacity-cs344-colab
!pip install git+git://github.com/depctg/nvcc4jupyter.git

# load cuda plugin
%config NVCCPluginV2.static_dir = True
%config NVCCPluginV2.relative_dir = "udacity-cs344-colab/src/HW1"
%load_ext nvcc_plugin

# change to work directory, generate makefiles
!mkdir udacity-cs344-colab/build
%cd udacity-cs344-colab/build
!cmake ../src

Could you please teach me about which command that finished the installation of the opencv?
