has no attribute 'get_sampling_map'

Hi,
Thank you very much for sharing your code. But when I run your code, the following error occurs:

/FreeViewSynthesis/exp/dataset.py", line 165, in base_getitem
sampling_maps, valid_depth_masks, valid_map_masks = ext.preprocess.get_sampling_map(
AttributeError: module 'ext.preprocess' has no attribute 'get_sampling_map'

Hope you can help answer, thank you.

Did you compile the Python extension as outlined in the readme?

cd ext/preprocess
cmake -DCMAKE_BUILD_TYPE=Release .
make 

[shuochen365]

yes，I have

[100%] Linking CXX shared module preprocess.cpython-38-x86_64-linux-gnu.so
[100%] Built target preprocess

[griegler]

What happens if you run python -c 'import preprocess' or python -c 'import preprocess; dir(preprocess)' in ext/preprocess?

[shuochen365]

/ext/preprocess$ python -c 'import preprocess; dir(preprocess)'
Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'preprocess'

[griegler]

That indicates that the extension has not been properly build. Maybe you are using a different Python version for building and running?

[shuochen365]

How much Python do you use ？ I use python 3.7.9

[griegler]

So python --version returns 3.7.9? Given your previous posting

[100%] Linking CXX shared module preprocess.cpython-38-x86_64-linux-gnu.so
[100%] Built target preprocess

you used Python 3.8 for building the extension. You might need to change the Python interpreter that cmake is using.

Ok, I will try again. Thank you very much.

Thank you very much for your kind answer. My problem has been solved.
