PyCharm cannot find library

I am using PyCharm 5 to run a Python 2.7 (Anaconda) script in Ubuntu. My script imports a module with import tensorflow, but this causes the error ImportError: libcudart.so.7.0: cannot open shared object file: No such file or directory. So, it seems that the library libcudart.so.7.0 is needed by this module, but it cannot be found.

Now, I have seen that this library is on my machine in /usr/local/cuda-7.0/targets/x86_64-linux/lib. So, in PyCharm, I went to Settings->Project Interpreters->Interpreter Paths. This had a list of paths, such as /home/karnivaurus/Libraries/Anaconda/python2.7. I then added to this list, the path mentioned above which contains the required library.

However, this did not fix the problem. I still get an error telling me that libcudart.so.7.0 cannot be found. If I run my script from the shell though (python myfile.py), then it runs fine.

How can I tell PyCharm where to find this library?

I have noticed that if I have print sys.path in my script, the paths it prints out are entirely different to those in Settings->Project Interpreters->Interpreter Paths... should they be the same?

The following works for me on Community edition 2019.3

To set globally for a project:

  • Open File/Settings/Project/Project Interpreter
  • click on the cog icon next to the interpreter
  • choose show all
  • click on the little folder with tree icon bottom right
  • add the path to "Interpreter Paths"

While some of these answers are correct, and could work, I haven't seen what the OP specifically asked for, and that is where to set environments for the python console. This can be accomplished inside pycharm at:

File > Settings > Build,Execution,Deployment > Console > Python Console

In the options there, you'll find a place to define Environment Variables. Set LD_LIBRARY_PATH there. enter image description here

Edit your pycharm.desktop, specify the environment variable in exec, like below:

[Desktop Entry]
Version=1.0
Type=Application
Name=Pycharm
Exec=env LD_LIBRARY_PATH=:/usr/local/cuda/lib64:/usr/local/cuda/lib64 /home/cwh/software/pycharm-2016.1.4/bin/pycharm.sh
Icon=/home/cwh/software/pycharm-2016.1.4/bin/pycharm.png
Name[zh_CN]=Pycharm

so pycharm will find cuda

I came across this problem just recently using a remote debugger, however I believe it's still the same solution. I just added the following to the Environment Variables section in the Run/Debug Configuration options found in Run > Edit Configurations... dialog: LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

Have you selected the right python interpreter in your project's settings? See here.

I had a similar issue and changing the interpreter solved it without having to create a new icon.

The path to your cuda library seems strange to me. I would expect it to be /usr/local/cuda-7.0/lib64 or /usr/local/cuda-7.0/lib.

Did you follow all of the cuda installation procedure?

If you type env on the command line, do you see a path to cuda in your LD_LIBRARY_PATH?

Update from comments below:

The issue is that PyCharm was invoked from the desktop, and wasn't getting the right environment variables. Solution is to either:

  • invoke from the command line,
  • create a script to set environment and then invoke, and make a link to that script on the desktop,
  • or set environment variables on the desktop item
