How to save the edited .nrrd files in python?

Question

So I am unable to save the resized nrrd file here

!pip install pynrrd
import numpy as np
import nrrd
import cv2
from PIL import Image
import matplotlib.pyplot as plt

readdata,header = nrrd.read("/content/drive/MyDrive/Colab Notebooks/Image/imagingVolume .nrrd")
print('readdata: ', readdata.shape) #(256,256,30)

readdata = cv2.resize(readdata,(192,256))
readdata = np.transpose(readdata, (2,0,1))
print(readdata.shape) #(30,256,192)
cv2.imwrite("/content/drive/MyDrive/Colab Notebooks/","reshaped.nrrd")

Overload resolution failed:

• img is not a numpy array, neither a scalar
• Expected Ptr<cv::UMat> for argument 'img'
