原因:数字太小的原因,溢出,计算过程中出现-inf,再做其他运算,结果还是-inf。当概率很小时,取对数后结果趋于负无穷大 解决:改变浮点数的精度 参考:(51条消息) RuntimeWarning: divide by zero encountered in log错误解决_旅途中的宽~的博客-CSDN博客
Python中"divide by zero encountered in log"错误的含义 在Python中,当尝试对0或负数执行对数运算时,会触发"divide by zero encountered in log"错误。这是因为对数函数的定义域是正数,不包括0和负数。对数运算本质上可以看作是一种特殊的除法运算,即求以某个正数为底、以目标数为真数的幂运算的指数。当目标数...
I hope you found this article helpful. NumPy’s ability to efficiently divide arrays by scalars is one of the many reasons it’s such a powerful tool for numerical computing in Python. Whether you’re working with financial data, scientific measurements, or image processing, these techniques wil...

再次运行命令python eqtl_prepare_expression.py data.tpm.gct data.reads_count.gct --tpm_threshold 0.1 --count_threshold 2 --sample_frac_threshold 0.2 --normalization_method tmm --output data.txt,没啥卵用~~,还是出现相同的报错,说明不是无效值导致的。
Steps to handle type exception in Python The steps to handle type exception in Python are: Step 1:We will take inputs from the user, two numbers. Step 2:If the entered data is not integer, throw an exception. Step 3:If the remainder is 0, throw divide by zero exception. ...
Post category:NumPy / Python Post last modified:March 27, 2024 Reading time:17 mins read In NumPy, the numpy.divide() function is used to divide the elements of one array by the elements of another array. It performs element-wise division, broadcasting the arrays if necessary. This function...
