关于tfkan的安装

[yelou2022]

你好，这是我目前看到的一个最好的关于kan的tensorflow实现，我在google colab也能初步运行起来，但是当我准备进行下一步研究时，在环境配置方面遇到了一些问题，由于国内限速的问题，使用pip进行安装的过程并不顺利，而这个库似乎也没被一些常用的镜像源添加，所以无法通过配置镜像进行安装，我看了一下版本要求，里面只列举tensorflow和keras，是否说明tfkan只依赖于这两个包，只要安装这两个符合要求的包，就能通过克隆库的方式直接使用？另外，你们是否有打算配置一个conda渠道，以便研究人员能通过conda来安装你们的库？我想这应该有利于推广你们的成果

祝好！

I build conda packages and you can try with:

conda install tfkan -c xaviercamel

The package has not been add into default channel for conda, so we need to add -c xaviercamel for now.

Hope this can help you😄

Best!

thanks, you are the best developer! @ZPZhou-lab
you can update the readme file, which will help more people.

I received an email and it seems that you have encountered some troubles in the environment configuration. The following steps may help u😊

• step 1: create a new env with conda

conda create -n tfkan python=3.9
conda activate tfkan

• step 2: install cudatoolkit and cudnn for GPU support

conda install -c conda-forge cudatoolkit=11.3.1 cudnn=8.2.1
 
mkdir -p $CONDA_PREFIX/etc/conda/activate.d
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/' > $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh

before next step, we need sign out and sign back (or close and re-open your terminal)

• step 3: install tensorflow and tfkan with conda

conda activate tfkan
conda install xaviercamel::tfkan tensorflow==2.12.0=gpu_py39hc0f3f85_0

The above process takes tensorFlow==2.12 as an example. When installing TensorFlow using Conda, please pay attention to the compatibility between tensorflow version and cudatoolkit, cudnn version, and remember to specify TensorFlow with GPU build (i.e. tensorflow==2.x.x=gpu_pyxxxxxxxxx)

• step 4: test installation

import tensorflow as tf
import tfkan
tf.config.list_physical_devices('GPU')

Now, you can use tensorflow and tfkan with GPU.

@ZPZhou-lab
I was pleasantly surprised by your reply efficiency. I tried your steps, but it still said that the GPU was unavailable. This may be a limitation of my platform environment, but I found an alternative solution:

1. create a tensorflow environment with a GPU version (mine is 2.6.0, python=3.9.7).
2. use the git command to clone the library (note: do not use the pip install command later).
3. modify the command to import tfkan:

from tfkan import layers
from tfkan.layers import DenseKAN, Conv1DKAN

replace with:

from tfkan.tfkan import layers
from tfkan.tfkan.layers import DenseKAN, Conv1DKAN

Through the above steps, I successfully ran tfkan in the 2.6.0 tensorflow-GPU environment, and now I am trying to apply the effect. I hope this can provide some help.

您好，在使用过程中我发现Conve3D会导致原先五维的输入数据变成四维，请问这是为什么？是故意这样设计的吗？您辛苦！

@ZPZhou-lab hello, this question needs you to explain.
