Sys.setenv("CUDA_HOME" = "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7") source("raw.githubusercontent.com") install.packages("torch") 重复安装了torch两次还是三次,然后莫名其妙就好了。 debug就是这样吧,有的时候搞不大明白,不过,能用就不要再改动!!!,不然下次再重新安装,可能遇到完...
NumPy Matrix transpose() Python numpy module is mostly used to work with arrays in Python. We can use the transpose() function to get the transpose of an array. import numpy as np arr1 = np.array([[1, 2, 3], [4, 5, 6]]) print(f'Original Array:\n{arr1}') arr1_transpose =...
