A cikin labarin da ke tafe za mu yi la'akari da yadda za mu iya shigar da TensorFlow akan Ubuntu (16.04/18.04). TensorFlow ɗakin karatu ne na lamba don koyon na'ura a cikin ɗayan ayyuka.

Idan muna son girka TensorFlow, ana iya girka shi a cikin ɗaukacin tsarin, a cikin wani yanayi mai kyau na Python, kamar akwatin Docker da sauransu. Hanya mafi sananne kuma mafi sauƙi don shigar TensorFlow shine watakila ta hanyar yanayin Python mai kyau, inda za'a iya ƙirƙirar muhalli da yawa cikin sauƙin sarrafawa. Wannan shine zaɓin da zamu gani a cikin layi masu zuwa.
Sanya TensorFlow akan Ubuntu
Za'a aiwatar da tsarin shigarwa na gaba akan tsarin Ubuntu 18.04. Da zarar an bayyana wannan, don fara shigar da TensorFlow, kawai ku bi waɗannan matakan:
Sanya Python
Tunda amfani da Python shine hanya mafi sauri kuma mafi sauƙi don gudanar da TensorFlow, bari girka shi. Tsoho, Python 3 ya zo tare da wuraren ajiya na Ubuntu, don haka girkawarsa bazai zama matsala ba.
para san irin nau'in Python da aka sanya akan Ubuntu, a cikin m (Ctrl + Alt + T) kawai ku aiwatar da umarnin:
python3 -V
Kamar yadda kake gani, akan kwamfutata ina da Python 3.6.9, kuma don wannan misalin zan ƙirƙiri yanayi mai kyau ta amfani da ƙirar venv. Don shigar da kunshin python3-venv wanda ke ba da damar haɓakar venv, a cikin wannan tashar za mu aiwatar da waɗannan umarnin:
sudo apt update; sudo apt install python3-venv
Wannan yakamata ya kunna yanayin Python mai kyau.
Fara Python Virtual Muhalli
Yanzu da yake mun san fasalin Python da aka sanya, bari ci gaba da ƙirƙirar shugabanci don TensorFlow. A cikin wannan tashar kawai zamu aiwatar da umarnin:
mkdir ~/TensorFlow
Sannan mu tafi matsawa cikin kundin adireshin da muka kirkira:
cd ~/TensorFlow
Daga cikin wannan kundin adireshin, za mu ƙirƙirar yanayin kamala na Python buga:
python3 -m venv venv
Bayan ƙirƙirar shi kawai zamu kunna shi:
source venv/bin/activate
TensorFlow yana buƙatar cewa kayan aikin daidaita kunshin Python su zama na 41.0.0 ko sama da haka. Za mu aiwatar Pip kamar haka don tabbatar da an sabunta shi zuwa sabuwar sigar:
pip install -U setuptools
Sanya TensorFlow
Yanzu da yake an ƙirƙira muhalli kuma an kunna shi, zamu iya fara shigarwa ne kawai. Domin shigar da sigar yanzu, wanda ya hada tallafi don katunan GPU tare da CUDA (Ubuntu da Windows), a cikin tashar da za mu yi amfani da pip buga:
pip install tensorflow
Akwai kuma ƙaramin kunshin CPU kawai:
pip install tensorflow-cpu
para sabunta TensorFlow zuwa sabon sigar, dole flagara tutar-haɓakawa ga umarnin:
pip install --upgrade pip pip install --upgrade tensorflow
Bayan kafuwa, to tabbatar cewa an saka TensorFlow za mu iya aiwatar da umarnin mai zuwa:
python -c 'import tensorflow as tf; print(tf.__version__)'
Wannan umarnin ya kamata ya nuna sigar TensorFlow da aka sanya. Domin duba koyawa na daban-daban game da TensorFlow, zamu iya zuwa gidan yanar gizon aikin.
Kashe Yanayin Python
Lokacin da muka gama da yanayin Python, kawai kuna aiwatar da umarnin kashewa:
deactivate
Bayan haka dole ne kawai mu share abin da aka kirkira TensorFlow, kuma wannan ya kamata ya share yanayin Python da muka kirkira don gudanar da TensorFlow. Don ƙarin bayani akan yadda ake amfani da TensorFlow, zaka iya ziyarci koyawa cewa sun buga a shafin yanar gizon su ko akan website mai tasowa na Google.
