"tensorflow" - TensorFlow Python Library
This section provides a tutorial example on how to install TensorFlow Python library, 'tensorflow'. A very simple TensorFlow application script, hello_tensor.py, is provided.
If you are ready to create your own neural networks with TensorFlow in Python language, you can start with this tutorial to download and install the "tensorflow" Python library.
1. Install TensorFlow Python library, "tensorflow", and required libraries:
herong$ python3 --version Python 3.8.0 herong$ sudo pip3 install numpy ... Successfully installed numpy-1.19.0 herong$ sudo pip3 install tensorflow ... Successfully installed absl-py-0.9.0 astor-0.8.1 gast-0.3.3 google-pasta-0.2.0 grpcio-1.30.0 h5py-2.10.0 importlib-metadata-1.7.0 keras-applications-1.0.8 keras-preprocessing-1.1.2 markdown-3.2.2 setuptools-49.2.0 tensorboard-1.14.0 tensorflow-1.14.0 tensorflow-estimator-1.14.0 termcolor-1.1.0 werkzeug-1.0.1 wheel-0.34.2 wrapt-1.12.1 zipp-3.1.0
2. Verify installations:
herong$ python3 Python 3.8.0 (v3.8.0:fa919fdf25, Oct 14 2019, 10:23:27) >>> import numpy as np >>> np.1.20 '1.19.0' >>> import tensorflow as tf >>> tf.1.20 '1.14.0'
3. Create and run a very simple TensorFlow script, hello_tensor.py:
herong$ type hello_tensor.py import tensorflow as tf m = tf.constant(["Hello world!"]) s = tf.Session() o = s.run(m) s.close() print(o) herong$ python3 hello_tensor.py /usr/local/lib/python3.6/site-packages/tensorflow/python/framework /dtypes.py:516: FutureWarning: Passing (type, 1) or '1type' as a synonym of type is deprecated; in a future version of numpy, it will be understood as (type, (1,)) / '(1,)type'. _np_qint8 = np.dtype([("qint8", np.int8, 1)]) ... [b'Hello world!']
Okay. "tensorflow" Python library is ready. We can build our own neural networks with TensorFlow now.
If you are getting error on installing "tensorflow" library dependencies, you can try to install it without any dependencies first. Then add them as needed one at a time.
herong$ sudo pip3 install tensorflow --no-deps Successfully installed tensorflow-1.14.0
