I want to be able to launch a python program simply by clicking an icon on the desktop. The program uses pycuda and the NVCC compiler from NVIDIA. I have created the following desktop file

[Desktop Entry]
Type=Application
Terminal=true
Name=Trial4
Icon=utilities-terminal
Exec=/home/mantis/Desktop/trial4.sh 2>~/Desktop/trial4.log
#Exec=python3 /home/mantis/Desktop/sandpit/Trial4.py 2>~/Desktop/trial4.log
Categories=Application;

The Exec command works fine from the command prompt, but when I try to run the desktop file, I get this in the error log:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/pytools-2019.1.1-py3.6.egg/pytools/prefork.py", line 50, in call_capture_output
    stderr=PIPE)

    raise child_exception_type(errno_num, err_msg, err_filename)

During handling of the above exception, another exception occurred:

Could anyone advise what the problem is?
