SSLError using pip install (to install tensorflow)

问题:

while installing TF, exception appeared:

File "/usr/local/lib/python2.7/dist-packages/pip/_vendor/cachecontrol/adapter.py", line 46, in send resp = super(CacheControlAdapter, self).send(request, **kw) File "/usr/local/lib/python2.7/dist-packages/pip/_vendor/requests/adapters.py", line 447, in send raise SSLError(e, request=request) SSLError: ("bad handshake: Error([('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')],)",)

command: pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.6.0-cp27-none-linux_x86_64.whl

I have no clue how to solve this. I was recently reinstalled pip, could reinstall cause it?

回答1:

SSL error can be solved by bellow steps for sure. Just download the wheel on your own and pip install.

# Ubuntu/Linux 64-bit, CPU only:

$ wget https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

$ sudo pip install --upgrade tensorflow-0.5.0-cp27-none-linux_x86_64.whl

# Ubuntu/Linux 64-bit, GPU enabled:

$ wget https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

$ sudo pip install --upgrade tensorflow-0.5.0-cp27-none-linux_x86_64.whl

Use the following version of certifi

pip2 install 'certifi==2015.4.28' --force-reinstall

after that there will be no more SSL errors.

For those working on macOS run from a terminal window..

- /Applications/Python\ 3.6/Install\Certificates.command

回答4:

This command worked for me

pip3 install --trusted-host pypi.python.org  --upgrade http://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.0.0-py3-none-any.whl

I made the request as http instead of https and I was able to bypass the ssl check. Hope this helps.

I think you need some security certificates.

Please try the following command.

sudo pip install requests[security]

If you get any error message, please uninstall and reinstall python-requests.

sudo pip uninstall requests
sudo apt-get install python-requests    

I hoped it will give you the certificates you need. Thanks.

I ran into this problem too, and in my case using curl to download manually didn't fix the problem. Curl reported this:

curl: (60) SSL certificate problem: certificate is not yet valid

The problem in my case turns out to have been my VM's clock – it was way behind. Resetting my VM's clock so the datetime was correct fixed the problem, and I was able to go right back to installing straight from pip.

I've added this note to a related GitHub issue filed for TensorFlow. This Unix StackExchange question ultimately led me to the answer.

I used Anaconda to run "py -m pip install --upgrade tensorflow" and it worked.
