Error when verifying aihwkit installation

[lorsonblair]

I was having the following error installing with miniconda3:

---

I got it to install "sucessfully" to my environment using pip: pip install aihwkit. However, when verifying the installation with the example code provided in the documentation, https://aihwkit.readthedocs.io/en/latest/install.html, I get the following error:

I'm using torch 1.13.1 and cuda 11.2

Hi @lorsonblair:
seems that your system is not correctly set up. You need to make sure that you compile in the same environment that you want to run it in. In fact your glibc version is not correct as the error message points out, which looks like an environment mismatch.

On a power system it might be best to directly compile it with (after cloning)

git clone [email protected]:IBM/aihwkit.git
cd aihwkit
make build flags="-DUSE_CUDA=ON -DRPU_BLAS=OpenBLAS"

Make sure that you have GCC >= 7 or so installed.

@maljoras, thanks for your reply. I'm installing on another system (linux-64) Ubuntu 22.04. I got the initial verification to work. I am however unable to compile the cuda version.

python setup.py install --user -j8 -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXPORT_COMPILE_COMMANDS=TRUE -DUSE_CUDA=ON -DRPU_BLAS=OpenBLAS
Traceback (most recent call last):

I followed the instruction in the advanced setup documentation which suggests creating a python virtual environment and cloning the github in there. I will attempt to fix the issue on the power 64 system once I get this one working.

Hi:
you need to install all necessary requirements first.
pip install -r requirements.txt
