Cannot import name 'std_data' from 'auvlib.data_tools'

[MichalMotylinski]

HI,
I am getting an error while trying to run a sample code.
ImportError: cannot import name 'std_data' from 'auvlib.data_tools' (/home/user126/Projects/auvlib/install/lib/auvlib/data_tools/init.py)

I am running Ubuntu 20.04 and I think I followed the building process correctly.

1. sudo apt-get install libcereal-dev libglfw3-dev libtinyxml2-dev libboost-all-dev libopencv-dev xorg-dev
2. git clone https://github.com/nilsbore/auvlib.git
3. git submodule update --init
4. mkdir build && cd build
5. cmake -DCMAKE_INSTALL_PREFIX=../install ..
6. make -j4 && make install

There are no errors during building apart from tinyxml2 and glfw.

When trying to run the sample code I am first adding path and then executing the sample code.
export PYTHONPATH=$PYTHONPATH:/home/user126/Projects/auvlib/install/lib

Are there any other dependencies needed or did I just missed a step while building?

Thanks!

Hi,

It looks like you are doing alright, but can you import other libararies from data_tools such as xtf_data, csv_data and so on? Is std_data is the only one you cannot import or?

Btw, are you using conda?

I use conda and meet the same problem. how to solve it?

If you are using conda, you need to specify it here:

auvlib/src/CMakeLists.txt

Line 78 in e7492aa

set(PYTHON_EXECUTABLE /usr/bin/python3)

Thank you for your answer but there are still some problems:

As we pointed out in the readme, you can ignore those errors and build and install the code.

Ignore the errors about the tinyxml2 and glfw targets not being in the export set; build files are still generated properly.

HI, I am getting an error while trying to run a sample code. ImportError: cannot import name 'std_data' from 'auvlib.data_tools' (/home/user126/Projects/auvlib/install/lib/auvlib/data_tools/init.py)

I am running Ubuntu 20.04 and I think I followed the building process correctly.

1. sudo apt-get install libcereal-dev libglfw3-dev libtinyxml2-dev libboost-all-dev libopencv-dev xorg-dev

2. git clone https://github.com/nilsbore/auvlib.git

3. git submodule update --init

4. mkdir build && cd build

5. cmake -DCMAKE_INSTALL_PREFIX=../install ..

6. make -j4 && make install

There are no errors during building apart from tinyxml2 and glfw.

When trying to run the sample code I am first adding path and then executing the sample code. export PYTHONPATH=$PYTHONPATH:/home/user126/Projects/auvlib/install/lib

Are there any other dependencies needed or did I just missed a step while building?

Thanks!

Hello, have you solved your problem? I also encountered the same problem. auvlib was successfully installed, but when I tried to apply from auvlib. data _ tools to import std_data in an example, I got an error: the reference 'std_data' could not be found in ' imported module auvlib. data _ tools'.
