truncation was not explicitly activated but `max_length` is provided a specific value, please use `truncation=true` to explicitly truncate examples to max length. defaulting to 'longest_first' truncation strategy. if you encode pairs of sequences (glue-style) with the tokenizer you can select ...
to output a double in c via printf, you should use %g or %lf (lf stands for "long float" which is a double, in fact float stands for single precision :D ) %g truncate to the least significant number, %lf do not. You can even use something like %.20g, so you are asking to...

C语言truncate()函数:改变文件大小头文件: #include <unistd> 定义函数: int truncate(const char * path, off_t length); 函数说明:truncate()会将参数path 指定的文件大小改为参数length 指定的大小. 如果原来的文件大小比参数length 大, 则超过的部分会被删去.
