I have found that on some of our older systems when the superbuild attempts to build  
openimagedenoise that one of the files is giving an error.

superbuild/openimagedenoise/src/scripts/resource\_to\_cpp.py

is failing on line 33

```
  with open(in_path, 'rb') as in_file, open(out_path, 'w') as out_file:

```

at the comma. I have found a workaround is to convert it to

```
  with open(in_path, 'rb') as in_file:
    with open(out_path, 'w') as out_file:

```

and then fix the indentations following these lines.  
I have included my working file that includes this fix.

[resource\_to\_cpp.py](https://discourse.paraview.org/uploads/short-url/fEthblUXKOKxpY9Mx8tbtBU78eE.py) (2.9 KB)

This seems to successfully address the issue.

Thanks,

Joe

Joe, thanks for the report. Out of curiousity, are you building with Python 2 or 3?

Cory,

You’re welcome. I am building with Python 3 for ParaView 5.7.0.

for ParaView 5.6.1 and below I have used Python 2, with Python 2

becoming deprecated by year’s end, I thought it was a good time to switch.

Thanks,

Joe
