I installed python3.9.1 on the Coral Dev Board using the instructions from:
https://linuxize.com/post/how-to-install-python-3-9-on-debian-10/
I did this because I was unable to locate a compiled package to install using pip or apt.
I had been using python 3.7 with an OpenCV program I was working on but I kept getting an error "Unable to initilize Qt platform plugin" with a recommendation to reinstall. I was also unable to upgrade python 3.7 to python 3.9.1.
I experienced a build error during the installation:
"Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381"
The build completed otherwise and I installed it. Python3.9.1 shows up as the current version (python 3.7 has NOT been uninstalled). I created a virtual environment and began trying to use pip install python packages like numpy. But I get the error:
"There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/numpy/(Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) -skipping"
I have found several posts about this SSL problem but not yet a fix for it.
So the new python3.9.1 installation is useless to me. Furthermore, researching this topic on this site, I've learned that Tensorflow is incompatible with python3.9.1 so Id like to remove it if only to recover the space it occupies.
this is my first time diving into emscripten and web assembly and I am having some trouble with the installation process. I tried following the directions for mac on emscriptens website and I am able to do the pull command from github with no problem. However when trying to install emscripten with the "./emsdk install latest" command line it keeps failing.
Been at this for hours and I have updated just about everything and re-downloaded python to make sure it is the newest version. This is the error message I am getting:
Error: Downloading URL 'https://storage.googleapis.com/webassembly/emscripten-releases-builds/deps/node-v14.18.2-darwin-x64.tar.gz': <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)>
Warning: Possibly SSL/TLS issue. Update or install Python SSL root certificates (2048-bit or greater) supplied in Python folder or https://pypi.org/project/certifi/ and try again.
error: installation failed!
Any help is much appreciated! Thank you!
Please do not use python2. Install certifi with pip3 install certifi. Then just browse to Applications/Python 3.x and double-click Install Certificates.command
Now you can continue the installation.
Do not use Python 3. You must use Python 2.
python3 ./emsdk.py install latest
python3 ./emsdk.py activate latest
python ./emsdk.py install latest
python ./emsdk.py activate latest

I am stuck using pip 1.4.1 and have run up against a problem when upgrading package.
Could not fetch URL https://pypi.python.org/simple/pymongo/: There was a problem confirming
the ssl certificate: <urlopen error [Errno 1] _ssl.c:509: error:1407742E:SSL
routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version>
I have seen that later versions of pip you can do --trusted-host to ignore the certs warning. But on 1.4.1 it appears that this option is not available. How to fix?
The worst problem in your case is not untrusted host, the worst problem is too old versions of Python and OpenSSL. Your pip tried to use protocol version TLS v1 which PyPI stopped supporting long ago.
To install packages over the Net you need to upgrade OpenSSL, Python and pip. If you cannot upgrade you cannot install from PyPI directly. Then you can try to download packages from PyPI using a browser and install them from the local filesystem.
You can also use pip download on a host with more modern OpenSSL/Python/pip, transfer downloaded packages to the ancient host and install them there. See https://stackoverflow.com/a/14447068/7976758
I am trying to setup emsdk on mac with the following command:
./emsdk install latest
I cloned the repo from git. However, I get the following error upon running the command mentioned above:
** NOTICE **: The default SDK changed from `fastcomp` to `upstream`.
If you have problems, or wish to revert back to fastcomp for some other reason
you can add `-fastcomp` to explicitly install that fastcomp-based
SDK, .e.g ./emsdk install latest-fastcomp.

I have tried running the following to fix this but it did not solve the issue.
pip install certifi
Any other suggestions to fix the issue would be quite welcome.
I was able to upgrade the python version to 3.8.0 using pyenv. The upgrade helped me with the certificate issue.
brew install pyenv
pyenv install 3.8.0
pyenv global 3.8.0
or if inside the emsdk directory:
pyenv local 3.8.0
The command ./emsdk install latest ran successfully after the python upgrade.
I have been trying to figure this out for a while now and for some reason I get stuck with an ssl issue and have no idea what is going on.
Problem:
I have installed python2.7 and easy_install2.7, but when trying to install pip with easy_install2.7 I get the following error.
[root#cops-wc-01]# /usr/local/bin/easy_install-2.7 pip
Searching for pip

It is trying to download, but this SSL cert verification failure is preventing it.
Does anyone know a way around this, or a way to resolve it?
Sorry if it is a noob question :)

If you missed this package.
On my device (that runs nix),
$ date showed ...1969
so I had to set the date to a more recent time :
$ date -s "26 MAR 2017 13:16:00"
Then the SSL error was gone.
YAS (Yet Another Solution)
I had the same issue.
Tried everything above.
My issue was fixed by upgrading pip and setuptools:
$ pip install -U pip setuptools
I also tried to add an entry in my ~/.pip/pip.conf file:
[global]
trusted=https://pypi.your.domain
Most likely pip does not have the required CA certificates to validate that.
You can force pip to use openssl's CAs to see if it helps.
The easiest solution that worked for me:
From https://pypi.python.org/pypi/pip, download 'pip-8.1.2.tar.gz'
Install it with pip, "pip install ./pip-8.1.2.tar.gz"
On the ubuntu server, the new version pip may be installed in a different location. If checking version with 'pip --version', it's still an older version one, like pip 1.5.6. To install a package with the new version pip, straightforwardly use the absolute path for convenience:
/home/tom/.local/bin/pip install ./gensim-0.13.1.tar.gz
Install dependencies one by one, errors like this below can be bypassed.
Download error on https://pypi.python.org/simple/pip/: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) -- Some packages may not be found!"
On macbook put this line in ~/.bash_profile:
export SSL_CERT_FILE=/usr/local/etc/openssl/cert.pem
And forget about this error.
Of course, if you don't have openssl - run brew install openssl. And don't forget to do . .bash_profile after first edit of .bash_profile.
I ran the following commands to resolve the issue:
$ curl https://bootstrap.pypa.io/get-pip.py >> get-pip.py
$ python get-pip.py
This upgraded pip to v9.0.3, and this version has no issues.
Since this is currently the top hit on Google for this issue I thought I would share my solution. As weird as it is. I'm on CentOS 7, Python3.6 although I believe it doesn't matter which Python version.
The SSLError / CERTIFICATE_VERIFY_FAILED was also happening for me when I ran a fresh copy of get-pip.py.
The solution was to run the install command with output piped to a file, so python get-pip.py &> output. I haven't had the time to find out why not having a TTY affects the environment for the script.
If you are running behind a web filter or firewall, please ensure SSL inspection/decryption is disabled or bypassed for the domain *.pythonhosted.org (or more specifically, files.pythonhosted.org). May also need to include pypi.org.
I'm running Python on an enterprise workstation and this has been the culprit in our environment across Windows and Linux hosts. Confirmed with our older system, a Broadcom ProxySG on prem web filter appliance, and later through Cisco's Umbrella Cloud Gateway/SIG product.
Cheers
I didn't realize that there is a command "python -M ensurepip after 7.9. This fixed my issue.
