Why am I getting NaN when it is a number?
NaN is the result of an operation that was supposed to return a number, but couldn't because of an error or undefined/empty value. For example, dividing zero by zero or attempting to parse a string that doesn't contain a valid number will result in NaN.Why am I getting NaN?

Why is my mean NaN?
Not a Number (NaN) is given when trying to perform calculations on part of an array that is not initialised. For example, if you have the following array: If you try and find the mean of this array then you will find that the results will be NaN. This is because it is trying to find the mean value of nothing.How do you avoid NaN values?
But putting NaN values directly into a requirement can be frought with problems and should usually be avoided. The most robust way to do this is by replacing NaN values with a special token and then requiring the token. Below, we define a custom NanToken object and use it to replace actual NaN values.Why does my code keep saying NaN?
NaN stands for "Not a Number" and it is a value that represents an undefined or unrepresentable result of a mathematical operation in coding. It is typically used to indicate that a mathematical operation or function resulted in an undefined or nonsensical value.What causes loss to be NaN?
Exploding gradients: your loss becomes too large to fit the numeric constraint so it becomes Nan. If this happens, you might want to check the range of your input data and possibly normalise it; add batchnorm layers; do gradient clipping. Maybe also try smaller learning rate.How do you deal with NaN data?

This has to do with types—NaN is still a numeric type. It just means that the value cannot be represented as a number, but it still belongs to the number type. NaN can't be equal to another NaN since their values may be different.How to handle NaN in C?
Thus, you can write a test for a NaN like this: if (x != x) printf ("x is a NaN\n"); This test works in GNU C, but some compilers might evaluate that test expression as false without properly checking for the NaN value.How to check if a number is NaN?
To tell if a value is NaN , use Number. isNaN() or isNaN() to most clearly determine whether a value is NaN — or, since NaN is the only value that compares unequal to itself, you can perform a self-comparison like x !== x . For more information about NaN and its comparison, see Equality comparison and sameness.Why is 0 0 NaN?
NaN means “Not a Number”, or an indefinite result. If you divide anything by 0, it's like asking how many groups of 0 you can make from X total items - the answer could be any countable infinity, or any number could be an answer that is technically accurate. So X/0 doesn't have a defined result.How to fix NaN in Python?
