Error "ImportError: no module named mux" in Python

I installed a module one month ago. At that time, I could import the module successfully.

Now, when I import this module, there is an ImportError,

>>> import anuga
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/home/lili/anuga_core/source/anuga/__init__.py", line 110, in <module> from anuga.file_conversion.urs2nc import urs2nc
    File "/home/lili/anuga_core/source/anuga/file_conversion/urs2nc.py", line 12, in <module>
        from mux import WAVEHEIGHT_MUX_LABEL, EAST_VELOCITY_LABEL, \
    ImportError: No module named mux

How could I solve this problem?

Solution

  • ImportError comes only when the module is not available in the list called sys.path. Since the current operating system is Linux based (I got an idea from the error message /home/lili), it is required to have mux.py in the path (i.e, sys.path). The mux.py file will be exactly similar to the file available in this link.

    `https://anuga.anu.edu.au/svn/anuga/trunk/anuga_core/source/anuga/file/mux.py`

    All these problems come when the installation of ANUGA is not proper.
