Correct way to install tensorflow v1 in virtual environment

Q&A
#1

I created a virtual environment and installed intel-tensorflow package but while importing tensorflow I get following error:

>>> import tensorflow
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tensorflow'

Steps that I tried are below:

user@clearos~/.virtualenvs $ python -m venv my_env
user@clearos~/.virtualenvs $ source my_env/bin/activate
(my_env) user@clearos~/.virtualenvs $ pip --no-cache-dir install intel-tensorflow

I downgraded pip to version 19.0 as mentioned in https://software.intel.com/en-us/articles/intel-optimization-for-tensorflow-installation-guide#inpage-nav-1-4 and tried again installing the tensorflow. Got the same module not found error.

I tried using --no-cache-dir option with pip install but got another error.

Can anybody please provide a solution ?

#3

Have you installed tensorflow in you virtual environment?

#4

yeah, thats what I’m trying to install using pip. Buts its not working.

#5

What I see in your log message is that you installed intel-tensorflow, not tensorflow.

#6

While installing normal tensorflow v1 , I get following error

(my_env) user@clearos~/.virtualenvs $ pip install tensorflow-cpu==1.15
Collecting tensorflow-cpu==1.15
  Could not find a version that satisfies the requirement tensorflow-cpu==1.15 (from versions: 2.2.0rc1, 2.2.0rc2)
No matching distribution found for tensorflow-cpu==1.15
You are using pip version 19.0, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
#7

The non-gpu tensorflow is called ‘tensorflow’ not ‘tensorflow-cpu’

#8

I tried with both, tensorflow and tensorflow-cpu. No success in either. Same error message.

(my_env) user@clearos~/.virtualenvs $ pip install tensorflow==1.15
Collecting tensorflow==1.15
  Could not find a version that satisfies the requirement tensorflow==1.15 (from versions: 2.2.0rc1, 2.2.0rc2)

#9

Your python version needs to be 3.5-3.7.

Ohh… missed the requirement. Thanks for pointing out.
Is there a way to install python3.7 in clear linux as I could not find any specific bundle for that. Also based on this thread https://community.clearlinux.org/t/best-way-to-install-a-specific-version-of-python-in-the-clearlinux-docker-container/2056 it appears that I can not downgrade python in clear linux. Any thoughts on how can I install python 3.7 ?

Install Pyenv (by yourself)

#12

@doct0rHu thanks for pointing towards pyenv. Really useful.
Also pyenv-virtualenv plugin lets you manage virtualenv fair simply.
