[Python]错误集合

#1 ValueError: matrices are not aligned

解答参见https://developer.aliyun.com/ask/275414

#2 ValueError: Unable to coerce to Series, length must be 3: given 10

解答:出自10*2的矩阵乘以2*1的矩阵

data.iloc[:, i] = data.iloc[:, parentIdx] * weight + noise * noiseRatio

如果该形式放到matlab中矩阵乘法就没问题了,但在python中报错了

此处的3是data.iloc[:,parentIdx] * weight得到10行3列的矩阵,10是指10行

改成data.iloc[:,parentIdx].dot(weight)就不出现该问题了

但是加上noise * noiseRatio仍然报错ValueError: Unable to coerce to Series, length must be 1: given 10

经分析,加号前半部分是pandas dataframe数据结构,加号后面noise是numpy数据结构

所以进行统一数据结构就不报错了,noise = pd.DataFrame(noise)

#3 ValueError: ndarray is not contiguous

更改前:#temp_x = mat(dataset.iloc[:, x]).reshape(l, 1)
更改后:temp_x = mat(dataset.iloc[:, x].values).reshape(l, 1)

#4 TypeError: unsupported format string passed to tuple.__format__

更改前:print(f'F1:{single_process():.3f}')

是只导出一个参数值,想修改后导出4个参数值,报错;修改后,新错误TypeError: not all arguments converted during string formatting

更改后:print('Accu:%.3f, Recall:%.3f, Precision:%.3f, F1:%.3f'%(single_process()))

#5 ModuleNotFoundError: No module named 'src.partion'

将src文件夹下的partion复制出来到与main函数同层文件夹
