s I had encountered errors when I tried to install cupy,on Ubuntu 18.04
I upgrade cudnn. Then I succeeded installation of cupy.
The following is a notes on the procedure.
- after uninstallation of existing pip, reinstall pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py -user -vv
python get-pip.py -user -vv
- install a recent cuda-toolkit
2-1. download the cuda toolkit from https://developer.nvidia.com/cuda-toolkit-archive
2.2 install cuda-toolkit
sudo dpkg -i cuda-repo-ubuntu1804-10-0-local-10.0.130-410.48_1.0-1_amd64.deb
sudo apt-key add /var/cuda-repo-10-0-local-10.0.130-410.48/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda
- install cudnn
3-1 download packages for ubuntu18.04 from https://developer.nvidia.com/rdp/cudn
n-download
3-2. install cudnn packages
sudo dpkg -i libcudnn7_7.3.1.20-1+cuda10.0_amd64.deb
sudo dpkg -i libcudnn7-dev_7.3.1.20-1+cuda10.0_amd64.deb
sudo dpkg -i libcudnn7-doc_7.3.1.20-1+cuda10.0_amd64.deb
3-3. replace the old cuda path with cuda-10.0 path
nano ~/.bashrc
' NVIDIA CUDA Toolkit
export PATH=/usr/local/cuda-10.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64:$LD_LIBRARY_PATH
source ~/.bashrc
echo $PATH |grep cuda
- install cupy
pip3 install -user cupy
python3
import cupy
import cupy.cudnn
failed.
modulenotfounderror: no module named ‘cupy.cudnn’
so I did the following
pip3 uninstall cupy
set $CUDA_PATH as /usr/local/cuda
pip3 -v install -user cupy -no-cache-dir
python3
import cupy
import cupy.cudnn
No error.
pip3管理のパッケージ一括更新
pip3 list -o |grep wheel | awk ‘{print $1}’ |xargs pip3 install ?user -U
As I had encountered errors when I tried to install cupy,
on Ubuntu 18.04
I upgrade cudnn. Then I succeeded installation of cupy.
The following is a notes on the procedure.
1. after uninstallation of existing pip, reinstall pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python3 get-pip.py --user -vv
python get-pip.py --user -vv
install a recent cuda-toolkit
2-0. You should insatll nvidia-drivers first. the followings.
2-1. download the cuda toolkit from
https://developer.nvidia.com/cuda-toolkit-archive
2.2 install cuda-toolkit
sudo dpkg -i cuda-repo-ubuntu1804-10-0-local-10.0.130-410.48_1.0-1_amd64.deb
sudo apt-key add /var/cuda-repo-10-0-local-10.0.130-410.48/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda
3.0 install cudnn
3-1 download packages for ubuntu18.04 from
https://developer.nvidia.com/rdp/cudnn-download
3-2. install cudnn packages
sudo dpkg -i libcudnn7_7.3.1.20-1+cuda10.0_amd64.deb
sudo dpkg -i libcudnn7-dev_7.3.1.20-1+cuda10.0_amd64.deb
sudo dpkg -i libcudnn7-doc_7.3.1.20-1+cuda10.0_amd64.deb
3-3. replace the old cuda path with cuda-10.0 path
nano ~/.bashrc
NVIDIA CUDA Toolkit
export PATH=/usr/local/cuda-10.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64:$LD_LIBRARY_PATH
source ~/.bashrc
echo $PATH |grep cuda
install cupy
pip3 install --user cupy
python3
import cupy
import cupy.cudnn
failed.
modulenotfounderror: no module named 'cupy.cudnn'
so I did the following
4.0 pip3 uninstall cupy
set $CUDA_PATH as /usr/local/cuda
pip3 -v install --user cupy --no-cache-dir
python3
import cupy
import cupy.cudnn
No error.
