Thefloat()function can be used to check if a string is a floating-point number in Python, actually, this method converts a string to a floating-point number however, we can use this to check string contains a f

In Python, you can also use the comparison operator != to check for NaN values. NaN values are considered unequal to all other values, including themselves. Consider the following example: value = float('nan') if value != value: print("Value is NaN") else: print("Value is not NaN")...
When trying to track down a NaN with checkify's "float" check, one device typically has the "original" error, but all devices have a NaN error, since the NaN's later propagate via collective operations. I was seeing the error from the collective operation without realizing that there was ...

The isna() function in pandas is used to check for NaN values. It has the following syntax. pandas.isna(object) Here, theobjectcan be a single python object or a list/array of python objects. If we pass a single python object to theisna()method as an input argument, it returns True...

先说说fp16和fp32,当前的深度学习框架大都采用的都是fp32来进行权重参数的存储,比如Python float的类型为双精度浮点数fp64,PyTorch Tensor的默认类型为单精度浮点数fp32。随着模型越来越大,加速训练模型的需求就产生了。在深度学习模型中使用fp32主要存在几个问题,第一模型尺寸大,训练的时候对显卡的显存要求高;第二...
