Hi All, there are very good reasons to use a virtual environment. One of them is you don't want to mess with your system files and potentially make your machine unbootable!
@mariotrevi https://github.com/mariotrevi The following error indicates that you don't have pip in your system. Error: Command '['/home/david/dbn/dbn_upper_bound/venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
As this StackOverflow post suggests (https://stackoverflow.com/questions/26215790/venv-doesnt-create-activate-script-python3), you can do the following
- Create a virtual environment without pip
- Add pip into this newly created virtual env
The steps are
- python3 -m venv --without-pip testvenv (creates a virtual env called testvenv)
- source test4/bin/activate (get inside the virtual env)
- curl https://bootstrap.pypa.io/get-pip.py | python (install pip)
- deactivate (get out of the venv)
- source test4/bin/activate (get back in the venv)
Hope this helps resolve. Let me know if you still have issues. But we need to make sure venv works and not be messing with the system files. Towards that end, I have to revert some recent changes in the import statement.
Thanks! The virtual environment is now working.
The latest problem is an SSL problem :
$ pip -V pip 9.0.1 from /home/david/dbn/dbn_upper_bound/venv/lib/python3.6/site-packages (python 3.6)
$ pip install -r python_requirements.txt [ENTER]
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Collecting numpy==1.14.0 (from -r python_requirements.txt (line 1)) Could not fetch URL https://pypi.python.org/simple/numpy/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping Could not find a version that satisfies the requirement numpy==1.14.0 (from -r python_requirements.txt (line 1)) (from versions: ) No matching distribution found for numpy==1.14.0 (from -r python_requirements.txt (line 1))
