Python Stuff to install on while working on server

Jupyter Server

Running jupyter

jupyter notebook --no-browser --port=1717
jupyter lab --port=1717

Connecting to server

ssh -L 1717:localhost:1717 pourmand@192.168.207.78

Using Conda is a better alternative

Don’t forget to add conda-forge channel

conda create -n venv python=3.8

The python part is necessary! If you don’t choose that, no python would be installed!

SSH-Copy-id

First make sure you have an ssh key in your computer. Then you have to copy it to server using following command:

ssh-copy-id -i ~/.ssh/id_rsa.pub pourmand@192.168.207.78

Also, you can first set .ssh/config file. Then use following command.

ssh-copy-id servername

nvidia-smi

pip install nvidia-htop
pip install nvitop
 
nvidia-htop.py
nvitop

nvidia-smi --query (--display)
nvidia-smi -q
nvidia-smi -i 0
nvidia-smi -i 0 -q -d "memory"
nvidia-smi --query-gpu='memory.free' --format=csv

Connect to Another GPU

• torch.device(‘cuda:0’) or torch.device(‘cuda:1’)

export CUDA_VISIBLE_DEVICES=1

CUDA_VISIBLE_DEVICES=1 ./cuda_executable

Not needed

Creating venv

virtualenv -p python3 venv
source venv/bin/activate

install multiple python kernels with multiple versions

Install pyenv
$curl[https://pyenv.run](https://pyenv.run/)|bashFollowtheinstructiontomodify/.bashrcInstallthelatestPythonfromsourcecode$ pyenv install 3.8.3
Check installed Python versions
$pyenvversionsSwitchPythonversion$ pyenv global 3.8.3
Check where Python is actually installed
$pyenvprefix/home/admin/.pyenv/versions/3.8.3CheckthecurrentPythonversion$ python -V
Python 3.8.3

Installing Kernel for jupyter (only once)

python -m venv myenv
source myenv/bin/activate

pip install ipykernel
python -m ipykernel install —user —name=myenv

after having pipenv

is this necessary? or even good?

You can switch to environment using
pipenv shell
see pipenv current environment setting
pipenv —venv
change pipenv current virtual environment
echo ~/myenv > .venv
