When trying to read a certain CSV dataset with "ray", the exception shown below thros reproducibly. Loading the same dataset directly using pyarrow or pandas, it gets read completely. The dataset is part of the "kaggle.com" competition "ISIC 2024 - Skin Cancer Detection with 3D-TBP". The...
利用csv_read命令读取数据文件时的数字精度的问题难以发现,还与Jupyter Notebook的默认显示精度是小数点后6位有关。对于Lat = 37.776540000000004类似这样的数值,由于csv读取时导致的小数点后n位不是零的情况,平时看到的打印出的数据和csv文件中的数据都正常,但查询时就无法查到数据,也是挺坑人的。这次也是若不是想看...

matlab中的csvread函数和csvwrite函数 在做kaggle练习赛时，遇到了要将csv⽂件在MATLAB中导⼊为向量，以及将向量导出到csv⽂件中的问题。其实解决这两个问题很简单，MATLAB有现成的函数，但是当你不知道具体是哪个函数时，会⽐较头疼。特此做记录如下，希望对⼤家有所帮助。1：将csv⽂件在MATLAB中导⼊...

pandas是一个开源的数据分析和数据处理工具,read_csv是pandas库中的一个函数,用于读取CSV文件并将其转换为DataFrame对象。在读取CSV文件时,有时候需要将某些列的数据类型转换为整数类型。 要将列转换为整数类型,可以使用read_csv函数的参数dtype来指定每列的数据类型。具体步骤如下: ...
