## Dear ParaView Team, I use Paraview to visualize gprMax data (ground penetrating radar). I get the following error message with Linux Mint:
## Traceback (last call): File “”, line 185, in File “/home/jan/Downloads/digital dike runner/ParaView-5.12.0-RC3-MPI-Linux-Python3.10-x86\_64/bin/../lib/python3.10/posixpath.py”, line 152, in dirname p = os.fspath(p) TypeError: expects str, bytes or os.PathLike object, not FileNameProperty
## and with Windows 11:
Traceback (last call):
File “”, line 185, in
File “C:\Program Files\ParaView 5.11.2\bin\lib\ntpath.py”, line 223, in dirname
return split(p)[0]
File “C:\Program Files\ParaView 5.11.2\bin\lib\ntpath.py”, line 185, in split
p = os.fspath(p)
TypeError: expects str, bytes or os.PathLike object, not FileNameProperty
This is a path error: How can this be fixed or which older python-gprMax-Parview version harmonizes?
best regards
Daniel

Welcome to the ParaView Discourse, @igel89.
Beginning with starting ParaView, what are the exact steps you are following that lead to this error?
The error is telling you that `p` in some code is passing in a FileNameProperty, which is an object that you can retrieve a path from, but is itself not a path. What is the Python code and where is it being defined?
If you have access to this code, change the `p` argument to `os.fspath(p)` to `p.GetElement(0)` and you should be good to go.

Thank you for your quick reply
I use the program gprMax which works on python with miniconda. see install
[http://docs.gprmax.com/en/latest/index.html](http://docs.gprmax.com/en/latest/index.html)
This program is integrated as a macro in Paraview
[http://docs.gprmax.com/en/latest/output.html#geometry-output](http://docs.gprmax.com/en/latest/output.html#geometry-output)
Execution of gprMax in miniconda
cd C:\Users\Igel\gprMax
conda activate gprMax
To test an animation with standard example:
[http://docs.gprmax.com/en/latest/examples\_advanced.html](http://docs.gprmax.com/en/latest/examples_advanced.html)
Since this is only a model and not an animation, the code for ‘snapshot’ is added as a loop ==\> .vti
[http://docs.gprmax.com/en/latest/input.html#snapshot](http://docs.gprmax.com/en/latest/input.html#snapshot)
#python:
for i in range(1, 31):
print(‘#snapshot: x1 y1 z1 x2 y2 z2 dx dy dz {} snapshot{}’.format((i/10)\*1e-9, i))
#end\_python:
Insert the parameters from the 14th line of heterogeneous\_soil.in
print(‘#snapshot: 0 0 0 0.15 0.15 0.1 0.001 0.001 0.001 {} snapshot{}’.format((i/10)\*1e-9, i))
Execute
python -m gprMax user\_models/heterogeneous\_soil.in
Start Paraview
File/Open: user\_models/snapshot1.vti
gprMax Macro activate
Previously the error message appeared here and when I change this from os.fspath(p) to p.GetElement(0) Paraview crashes.

I have this error, too. The error appears because I forgot to click Apply for the vti file in the Pipeline Browser. After clicking Apply, I run the gprmax\_info macro.
