To compile from source, you need an installation of CUDA. If `nvcc` is not installed, you can install the CUDA Toolkit with nvcc through the following commands.
# EXPORT_TO_BASH in {0, 1} with 0=False and 1=True
# For example, the following installs CUDA 11.8 to ~/local/cuda-11.8 and exports the path to your .bashrc
bash cuda install 118 ~/local 1
# For example, the following installs CUDA 11.7 to ~/local/cuda-11.7 and exports the path to your .bashrc
bash install_cuda.sh 117 ~/local 1
```
To use a specific CUDA version just for a single compile run, you can set the variable `CUDA_HOME`, for example the following command compiles `libbitsandbytes_cuda117.so` using compiler flags for cuda11x with the cuda version at `~/local/cuda-11.7`:
self.add_log_entry('CUDA SETUP: Solution 1b): Once the library is found add it to the LD_LIBRARY_PATH: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:FOUND_PATH_FROM_1a')
self.add_log_entry('CUDA SETUP: Solution 1c): For a permanent solution add the export from 1b into your .bashrc file, located at ~/.bashrc')
self.add_log_entry('CUDA SETUP: Solution 2: If no library was found in step 1a) you need to install CUDA.')
self.add_log_entry('CUDA SETUP: Solution 2a): Download CUDA install script: wget https://github.com/TimDettmers/bitsandbytes/blob/main/cuda_install.sh')
self.add_log_entry('CUDA SETUP: Solution 2b): Install desired CUDA version to desired location. The syntax is bash cuda_install.sh CUDA_VERSION PATH_TO_INSTALL_INTO.')
self.add_log_entry('CUDA SETUP: Solution 2b): For example, "bash cuda_install.sh 113 ~/local/" will download CUDA 11.3 and install into the folder ~/local')
self.add_log_entry('CUDA SETUP: Solution 2a): Download CUDA install script: wget https://github.com/TimDettmers/bitsandbytes/blob/main/install_cuda.sh')
self.add_log_entry('CUDA SETUP: Solution 2b): Install desired CUDA version to desired location. The syntax is bash install_cuda.sh CUDA_VERSION PATH_TO_INSTALL_INTO.')
self.add_log_entry('CUDA SETUP: Solution 2b): For example, "bash install_cuda.sh 113 ~/local/" will download CUDA 11.3 and install into the folder ~/local')
# EXPORT_TO_BASH in {0, 1} with 0=False and 1=True
# For example, the following installs CUDA 11.7 to ~/local/cuda-11.7 and exports the path to your .bashrc
bash cuda install 117 ~/local 1
bash install_cuda.sh 117 ~/local 1
```
By default, the Makefile will look at your `CUDA_HOME` environmental variable to find your CUDA version for compiling the library. If this path is not set it is inferred from the path of your `nvcc` compiler.
