AttributeError: module 'cow_csvw.converter' has no attribute 'csvw'

[matiasf]

Hi COW team!

I have been trying to execute the CLI on a file to transform a CSV to Turtle but I couldn't install it properly following the instruction on the page. Also digging the repository found this quick tutorial https://github.com/clariah/cow_tutorial but have the same results. I think I need some dependency I'm missing but can't understand wich one.

This is the stacktrace:

Traceback (most recent call last):
  File "/home/vector/.local/lib/python3.6/site-packages/cow_csvw/csvw_tool.py", line 5, in <module>
    from converter.csvw import CSVWConverter, build_schema, extensions

During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named 'converter'

During handling of the above exception, another exception occurred:

    import cow_csvw.converter.csvw as csvw
AttributeError: module 'cow_csvw.converter' has no attribute 'csvw'

I try also installing this one pip3 install converter, but is installed on a python 2 version and doesn't work, probably isn't the correct one.

Any help will be appreciated :)

hi Matthias,

sorry for the CoW moohing at you.

Just to make sure:

• you yourself have python 3?
• you ran pip3 install cow-csvw?
• next you ran cow_tool --version and that did not provide you 1.0.2?

I'm not sure if I understand you correctly, but indeed CoW ceased to work under Python 2.

Hi Richard, thanks for your quick response.

Checking your recommended list I have this results:

"you yourself have python 3?"
It, is installed

I run it, here the installation log:

"next you ran cow_tool --version and that did not provide you 1.0.2?"
Here I have the same trouble

AttributeError: module 'cow_csvw.converter' has no attribute 'csvw'

All is correctly installed with python3, after seeing this error I thought it was a dependency issue with converter library for the message ModuleNotFoundError: No module named 'converter'

In that moment I run pip3 install converter

➜  cow_tutorial git:(main) pip3 install converter
Collecting converter
Installing collected packages: converter
Successfully installed converter-1.0.0

But this package doesn't work because is old python2 package for the this error:

➜  cow_tutorial git:(main) cow_tool --version    
Traceback (most recent call last):
  File "/home/vector/.local/bin/cow_tool", line 7, in <module>

                                         ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(" This is the metric converter ")?

After that I uninstall this converter package, but return to the first error.
