false, then it will be a ValueError to serialize out of range float values (nan, inf, -inf) in strict compliance of the JSON specification, instead of using the JavaScript equivalents (NaN, Infinity, -Infinity). indent:应该是个非负的整型,如果是0就是顶格分行显示,如果为空就是一行最紧凑显示...

defon_change(self):ifself.name.get().strip(): self.hello_string.set("Hello "+ self.name.get())else: self.hello_string.set("Hello World") 要获取文本输入的值,我们调用其文本变量的get()方法。如果这个变量包含任何字符(请注意我们去除了空格),我们将设置我们的问候文本来问候输入的名字;否则,我们...
Options are 0, 1, 2, and any value greater than or equal to GRB.INFINITY. name –(string, optional) Name for the new general constraint. Note that name will be stored as an ASCII string. Thus, a name like ‘A\({\rightarrow}\)B’ will produce an error, because ‘\({\rightarrow...

情况不重要,因此,例如,“inf”,“Inf”,“INFINITY”和“iNfINity”都是正无穷大的可接受拼写。 否则,如果参数是整数或浮点数,则返回具有相同值(在Python的浮点精度内)的浮点数。如果参数在Python浮点数的范围之外,则引发一个OverflowError。 对于一般的Python对象x,float(x)委托给x .__float__()。 如果没有给...
The constant returns the value of a floating-point positive infinity.Example 1In the following example, we are initializing a variable "max_value" with positive infinity (math.inf). This can be useful in situations where you want to ensure a variable holds the maximum possible value and you ...
Infinity –Enables deployment of any embedding, reranking, CLIP, CLAP, and sentence-transformer model from HuggingFace with optimized inference backends. Supports multiple inference engines including PyTorch, ONNX/TensorRT, and CTranslate2, utilizing hardware accelerators like NVIDIA CUDA, AMD ROCM, CPU...
