numpy中nan_to_num()函数能很方便的将nan、inf值填充成统一的值。但在实际使用的时候发现有时候nan值怎么都填充不了,不确定是不是bug,但还是会影响开发进度,所以记录一下。 填充后的矩阵如下图所示: 检查代码后发现是因为数据中混入了一些str格式的数据,当矩阵中的元素不全是数值类型时,nan_to_num()是不会...

I have checked the existing issues. Describe the feature you'd like Now, the INSERT interface of infinity-sdk only support python native list. Many users use numpy array as the embedding model output. Therefore, it is better that infinity-sdk supports numpy array as the INSERT vector input ...
Using `pip install` and `import infinity`, you can quickly build a local AI application in Python, leveraging the world's fastest and the most powerful RAG database: 1. Install Infinity as a module: 1. Install Infinity as a Python module: ```bash pip install infinity-sdk==0.3.0.dev5...
