[size=15.0667px]使用numpy.mean()时发生错误
def zeroMean(da**at):
meanVal = np.mean(da**at, axis=0)
newData = da**at - meanVal
return newData, meanVal
错误提示如下[size=15.0667px]File "C:\Users\GuPeishang\PycharmProjects\tensorflow_train_HAR_text\utils\PCA_text.py", line 12, in pca newData, meanVal = zeroMean(da**at) [size=15.0667px]File "C:\Users\GuPeishang\PycharmProjects\tensorflow_train_HAR_text\utils\PCA_text.py", line 7, in zeroMean meanVal = np.mean(da**at, axis=0) # 按列求均值，即求各个特征的均值
