SSL error while using pip install to install tensorflow-gpu - ssl

I am trying to install tensorflow-gpu by running pip install tensorflow-gpu Windows, inside an Anaconda enviornment, but I am getting the following error:
Could not install packages due to an EnvironmentError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:1977)
I also tried doing it in a command prompt with administrator access, but it still didn't work.
C:\WINDOWS\system32>pip install tensorflow-gpu

Could not install packages due to an EnvironmentError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:1977)
All other network-related activities(such as browsing the web) work properly on the computer. I also have the correct CUDA and cuDNN installed, along with the latest NVIDIA drivers.
I fixed this problem by purging my Anaconda installation and reinstalling it, and then installing tensorflow-gpu. However, I am still curious as to why this error even happened in the first place.


It's related to network connection. I faced the same error in my Ubuntu system. Hence solved it by changing my network(WiFi) connection.


Use the following syntax while installation packages:
pip install --user packagename


I had the same problem with PyCharm to install tensorflow. As Dimitri Bolt described, I started the CMD as administrator and used the sytax described by Devendra Kanade. I got the error again, but each time I started the command, the progress became bigger. After three or four times, the download was successful and I was able to import tensorflow in PyCharm.


You should note "Downloading" (19%, not finished yet) in the pip-msg just before the error. For pip, this means 99% that this is a download error.
The quick fix is to increase <retries> in the pip option :
--retries <retries> Maximum number of retries each connection should attempt (default 5 times).
NB: I've never tried this.
The general fix using normal download (I tried this to install PyQt5) :
a) Find the name of the problematic web-file in your pip-errmsg, enclosed in quotes, then google the whole (including quotes). In your case, that will be "tensorflow_gpu-1.9.0-cp35-cp35m-win_amd64.whl" .
b) Choose a reliable site and download that file. Windows 10 may give you erroneous msg about some .part-file but just ignore that msg and download again.
c) Load your browser list for downloaded files. For Firefox, ctrl-J will load that list (library). If failure, click to repeat download on the list (not site). You may need to repeat the clicking 10 times for the download to be successful !!!
d) Suppose that "tensorflow_gpu-1.9.0-cp35-cp35m-win_amd64.whl" is now in the local folder c:\Users\uuuu\Downloads\ .
Create in this folder an ansi-text file named "example-requirements.txt" which has 3 lines(2 empty lines) as below:
tensorflow_gpu-1.9.0-cp35-cp35m-win_amd64.whl
e) Now in a normal command prompt, issue 3 commands as below:
c:
cd c:\Users\uuuu\Downloads\
pip install --requirement example-requirements.txt --no-cache-dir
NB: you can copy and paste, very easy in Win 10.
f) If successful, done now !
g) If you again have pip-problem with downloading another web-file then you must repeat a) , b) , c) , d) and edit the old "example-requirements.txt" to contain 4 lines(2 empty lines) as below:
tensorflow_gpu-1.9.0-cp35-cp35m-win_amd64.whl
another-file-name-with-extension
h) Repeat e) , f) , g) ... ...
NB: DOC for pip install-options are found on https://pip.pypa.io/en/stable/cli/pip_install/#
(search for "Example Requirements File" on the page).


stumbled upon the same error while installing via conda, updating conda solved the problem (btw, the new version downloaded the packages sequentially, whilst the older attempted a parallel download)


Reinstall the library again!
I face this problem for several libraries like tensorflow-gpu and matplotlib
I have no idea why but if i found something i will share.

Python Download Location (Windows) :
Python (for Windows) can be download from the following location :
https://www.python.org/downloads/

I'm on VS Code in Windows 10, and here's how I solved it.
You need to pay attention to where the Python is located (in my case),
1) C:\Users\_Me_\AppData\Local\Programs\Python\Python38\
and where the Python looks for libraries/packages, including the ones installed using pip (again, in my case),
2) C:\Users\_Me_\AppData\Roaming\Python\Python38\
I don't know why these two locations are different (gotta fix it at some point). It seemed that Python was running from the first location, but it was looking for libraries in the second!:/
Anyway, since I have limited experience in Python , I just copied the \Lib\site-packages from the first location (including selenium folders) to \site-packages in second one in hopes of solving the issue, which worked out for me!
How to check for there locations
1) Open Python CLI, typed the following command:
which python
2) Open Python CLI, typed the following commands (From this answer):
>>> import site
>>> site.USER_SITE
EDIT
Since this seems a temporary solution, I uninstalled Python and reinstalled it again in a proper directory (other than the default install directory), and now which python and which pip point to the same folder! Problem solved!

If these solutions did not work for you, try looking into which Python interpreter your IDE is using (in my case I was using VSCode - you can find the interpreter in the bottom bar). Worked for me.

Easiest way is to copy all files of "venv" Lib, Scripts, Selenium and other folder into your main project folder.
This issue occur as pycharm directly take from virtual environment venv.
Hope this will resolve your problem :)

conan io : Unknown command 'export-pkg'

I am using conan io to create a package from pre build binaries. I found this post on the conan website: http://docs.conan.io/en/latest/creating_packages/existing_binaries.html but the problem is: Every time I try to use export-pkg command I get an error that this command is unknown. What is more I can neither create a --bare package. What is wrong?
Do you have any idea what commands to use?
Thank you in advance,
K.

So, it occured that I had a prehistoric version of conan. What was surprising because couple of minutes before I upgraded conan. What happened: the upgrade was not successfull (although eveyrthing looked fine) because I had installed pythonx86. As soon as I installed pythonx64 and re-upgraded conan I had access to these new commands,
just in case someone had similar issues....

Creating network files in SUMO using NETCONVERT

Problem when calling netconvert in sumo:
I am trying to create my own scenario for simulation purposes.
I am using OpenStreetMaps for this.
python osmWebWizard.py
opens the browser and I select the area which I download.
netconvert --osm-files osm_bbox.osm.xml -o osm.net.xml
The error message I get is
Error: Cannot import network data without PROJ-Library. Please install packages proj before building sumo
Warning: Environment variable SUMO_HOME is not set, using built in type maps.
Quitting (on error).
My attempt to fix the problem is:
sudo apt-get install libproj*
But it seems like a dead end there and I am out of options.
Thank you.
EDIT
I have a gut feeling it has to do with libproj0 not being available anymore.

Systemtap libdwfl error on Linux

I am tying to work/setup the Systemtap tool for profiling OS procesess, on a Virtual Linux. I am using VirtualBox to run the image. Via
rpm -q kernel
and
cat /proc/version
The version obtained is:
Linux version 2.6.32-5-686 (Debian 2.6.32-48squeeze4)
I have correctly downloaded and installed the tool and wrote a simple program (.stp). However I keep getting the same error, which I have searched information in many places without success:
After executing:
sudo stap my_profiler.stp
I get:
semantic error: libdwfl failure (all kernel modules found): no error
Pass 3: translation failed. Try again with another '--vp 001' option.
According to https://sourceware.org/systemtap/SystemTap_Beginners_Guide/errors.html
⁠semantic error: libdwfl failure
There was a problem processing the debugging information. In most cases, this error results from the installation of a kernel-debuginfo package whose version does not match the probed kernel exactly. The installed kernel-debuginfo package itself may have some consistency or correctness problems.
I have found no relevant information on the "kernel-debuginfo" package. I have also tried the verbose option without benefit. I even tried with an old Snapshot of the VM. Any ideas?
The code of the .stp program I ran:
probe timer.profile{
printf("Process: %s\n", execname())
printf("Process ID: %d\n", pid())
}

Found the problem!!!! It seemed that I was using the wrong version of the Linux Kernel. I was using the default kernel supplied by the version I wrote in the question. It seems that that version (the 2.6.32-5-686 one) has problems with the debug-info so all I did was try the same with another version (the Linux version 3.9.6 with gcc version 4.7.2 Debian 4.7.2-5) and it worked without trouble :)

error while running apt-get update probably incorrect release file causing apt-get update to fail

I've been using elementary OS 0.3 Freya (64-bit) built on Ubuntu 14.04
When I tried to open Software Updater its showing Failed to download repository information
and when I tried to run
sudo apt-get update
this is what it prints:
W: Failed to fetch http://in.archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)
E: Some index files failed to download. They have been ignored, or old ones used instead.
I donno whats the problem and I cann't find a solution for this while I googled it.

From what I've read on the issue, one of the repositories has failed. Maybe try removing them one at a time and see if you can find the offending one.
Edit the ppa's and change freya to trusty. Not sure if this is the ideal solution, but it fixes it.

I removed Chrome download/update from the download list and changed the Ubuntu Software Settings in column 1 to Download from main server. It did the download and update this way.
