This is a path variable that specifies the location of the CUDA toolkit and the NVCC compiler.
/usr/local/cuda is the directory where the CUDA toolkit is installed. It contains various files and directories related to CUDA, such as libraries, header files, and binaries.
/usr/local/cuda/bin/nvcc is the location of the NVCC compiler, which is used to compile CUDA programs. It is located in the bin directory of the CUDA installation.
By including this path variable in the system's environment variables, the system can easily locate and use the CUDA toolkit and NVCC compiler when compiling and running CUDA programs.

No such file or directory: ':/usr/local/cuda:/usr/local/cuda/bin/nvcc'
This error message indicates that the file or directory ':/usr/local/cuda:/usr/local/cuda/bin/nvcc' cannot be found. It is likely that there is a mistake in the path or that the file or directory has been deleted or moved.
To resolve this issue, you can try the following steps:
1. Check the path: Make sure that the path is correct and that there are no typos or errors. You can use the 'ls' command to list the contents of the directory and check if the file or directory exists.
2. Check if CUDA is installed: If you are trying to access the CUDA directory, make sure that CUDA is installed on your system. You can check this by running the 'nvcc -V' command in your terminal. If CUDA is not installed, you will need to download and install it.
3. Update the environment variables: If the path is correct and CUDA is installed, you may need to update your environment variables. Check that the PATH variable includes the correct paths for CUDA and make sure that it is set up correctly.
4. Reinstall CUDA: If none of the above steps work, you may need to reinstall CUDA. Make sure to follow the installation instructions carefully and check that everything is set up correctly.

这个错误信息可能是由于缺少CUDA库或者安装路径不正确导致的。请检查一下你的CUDA相关配置是否正确。
首先,你需要确认你的CUDA是否已经正确安装,并且CUDA的安装路径是否正确。你可以在终端中输入以下命令来检查CUDA的安装情况:
```
nvcc -V
```
如果你能够看到类似于以下的输出,则说明CUDA已经成功安装:
```
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Sun_Jul_28_19:07:16_PDT_2019
Cuda compilation tools, release 10.1, V10.1.243
```
如果你没有看到上述输出,那么你需要重新安装CUDA。
如果你确认CUDA已经正确安装,但是仍然遇到了这个错误信息,那么你需要检查一下环境变量是否正确设置。你可以在终端中输入以下命令来检查环境变量:
```
echo $LD_LIBRARY_PATH
```
如果你能够看到类似于以下的输出,则说明LD_LIBRARY_PATH环境变量已经正确设置:
```
/usr/local/cuda/lib64:/usr/local/cuda-10.1/lib64
```
如果你没有看到上述输出,那么你需要手动设置LD_LIBRARY_PATH环境变量。你可以在终端中输入以下命令来设置环境变量:
```
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda-10.1/lib64
```
请注意,以上路径仅供参考,具体路径需要根据你实际的CUDA安装路径进行修改。
