I am trying to get mujoco_py running. When I do
import mujoco_py
I get this error:
Exception:
Missing path to your environment variable.
Current values LD_LIBRARY_PATH=
Please add following line to .bashrc:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/jonah/.mujoco/mjpro150/bin
I have added the above line to both /etc/skel/.bashrc and ~/.bashrc. If I run
echo $LD_LIBRARY_PATH
I get
/home/jonah/.mujoco/mjpro150/bin/
My .mujoco folder includes mjkey.txt and the mjpro150 folder. I can run ./simulate successfully, so I have a feeling that this is some kind of mujoco_py specific bug.
Which program do you use to import mujoco?
I had a similar issue using mujoco_py with PyCharm Community 2018.1. A workaround was to launch PyCharm from the terminal instead of using the launcher icon. Maybe it could help with your issue too.
Otherwise you could try adding the LD_LIBRARY_PATH to ~/.profile instead of ~/.bashrc, as proposed in this answer here: https://askubuntu.com/questions/1022836/python-not-recognizing-ld-library-path/1022913#1022913
You can try to reinstall Pycharm for the newest version.
After you save the .bashrc file your want execute this code.
source ~/.bashrc
Now link is updated.
Please check the user which you run the code with. The mismatch user will cause this problem. There is the checklist may help you:
Don’t use ‘sudo’ to run the code;
Don’t use ‘sudo’ or virtual environment (e.g., anaconda) to run Pycharm (If you run the code in Pycharm).

I'm trying to install some development platform on Ubuntu 20.04. Here is what was said on the install-manual:
check the screenshot here :D
I'm not sure what to do now. It seems that I should modify the $CMAKE_PREFIX_PATH by creating a "nrp_variable" in the .bashrc file. But I don't know the syntax, which could achieve it correctly.
CMAKE_PREFIX_PATH is environment variable and you can just run printenv CMAKE_PREFIX_PATH to see content.
Also to solve issue try running command in green box.
I made a virtualenv with tensorflow installed and I changed Python interpreter set to the location where the virtualenv is located at. When I ran the program, it gives the error:
ImportError: libcudnn.so.5: cannot open shared object file: No such file or directory
I have the following lines written in my .bashrc file
export CUDA_HOME=/usr/local/cuda-8.0
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64:$LD_LIBRARY_PATH
export PATH=${CUDA_HOME}/bin:${PATH}
Also, I found the libcudnn.so.5 file in the following path:
/usr/local/cuda-8.0/lib64
I encountered this error before I opened PyCharm and I did manage to install the correct cudnn version. The problem is, I can use
$ source [virtualenv_path]
to active the virtualenv and run python in terminal and everything works fine, no errors shown. The program also runs without error in Pycharm's terminal but it just gives me the above error whenever I click the run button. Could there still be something wrong with the environment variable? How do I fix it?
Unfortunately in pycharm you have to set CUDA_HOME and LD_LIBRARY_PATH inside the IDE. To do that go to the Run menu->edit configurations then choose your project. Then you click on the Environment Variables and add an entry for CUDA_HOME and LD_LIBRARY_PATH. When you have done that you can run directly from inside pycharm. I would also recommend setting the defaults to have these paths as well, so you don't have to do this for every project. Also it wouldn't hurt to make sure you have the interpreter from source [virtualenv_path] set while you are on this setting page. Let me know if you have trouble finding where to do this.
I've read this other Stackoverflow post: Pycharm environment different than command line, and it seems that the problem is that openning PyCharm in the normal way won't preserve the bash environment. The solution is to open PyCharm from the command line and everything works now. All you need to do is to open PyCharm using charm and everything works fine now.
I have searched a lot, but I didn't find the right solution for this question anywhere. I found the solution with my friends and I would like to share with you also.
If your Tensorflow works in terminal properly but doesn't work in Pycharm you have two solutions:
1- Open Pycharm from Terminal. For me:
pycharm-community
2- If you are using Unity, you need to edit .profile, because Pycharm doesn't preserve .bashrc: So, open a terminal and type:
gedit .profile
Then, add the following codes at the end of the opened file:
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
Save and exit. Now, you can work with Tensorflow in Pycharm without the necessity of opening the Pycharm form terminal.
I Installed Ubuntu 14-04 LTS. I tried to install software's using Terminal.Each time Software Installation successful but after installation it always diSlays one command which is '-System-Product-Name:~$ '.I applied many this like my computer name etc.But not yet success.
I am new in Linux platform.Anyone aware solution for the same please help me.Thanks In advance
Add the following line to .bashrc file in your /home/your-username folder
export PS1="\[\e[0;32m\]\u#\h:\e[m\] \[\e[1;34m\]\w$\e[0m "
execute the command
source .bashrc
Then read

System-Product-Name is the default hostname.
To change it, you can run sudo nano /etc/hostname, modify it with something like yourname-desktop
Background: I am trying to run a windows-installed version of python from within cygwin, rather than the cygwin version (some packages I am using prefer the non-cygwin version). The following post got me up and running: Using Windows Python from Cygwin. However, I am now having an issue.
Problem: The PYTHONPATH variable does not seem to be working for me. I try "import module1" when I am using python in an arbitrary directory. module1 is located here: c:\cygwin\home\mcsefl\testFolder\module1.py. And my PYTHONPATH variable is set in my .bashrc file in the following way: "export PYTHONPATH=$PYTHONPATH:/home/mcsefl/testFolder". However I still get a "No module named..." error.
Alternate tries: Since I am running the Windows Python, I thought perhaps python did not care about the cygwin environment variables (not sure if this is true..?) So, I also tried to set the windows PYTHONPATH env variable in the control panel of windows with no luck as well.
Thanks in advance
I deleted the line in my .bashrc file that tried to set the PYTHONPATH variable and just let it be set by Windows. This corrects the problem.
Side note: The title for this Question is a misnomer now that I re-read it. My issue was resolved without addressing that overall question
I'm followint these instructions to install Kile+TexLive 2010 with package manager on my Ubuntu Maverick: http://ubuntuforums.org/showthread.php?t=141934
The problem I have is that when I finish downloading all the packages to my computer, I have to edit the path but Ubuntu doesn't recognize it. The lines are the following:
PATH=/usr/local/texlive/2005/bin/i386-linux:$PATH
export PATH
I run echo $PATH and as long as I don't close the terminal, the path appears with the echoing, but if I close it, the path disappears. Nevertheless (whether I close the terminal or not), I'm supposed to run texhash but I am told that the command is not found. I already tried editing the path by adding the two lines above to both .bashrc in my home directory and to bash.bashrc in /etc/ directory.
I'm just following the instructions linked above, but I'm a linux rookie. Could anyone help, please?
in order to permanently change any environment variable under Ubuntu/Linux, you must modify the files you mentioned (for example ~/.profile). If you simply issue an export via the terminal, its effect will end once the terminal is closed. Sometime it is needed to perform a logout/login for the changes to take effect.
Also, mind the syntax of what you write in the above mentioned file(s), like "'s around $PATH.
