TypeError: Image data can not convert to float

问题:

I want to create an 16 bit image. So i have written a code.

     import skimage       import random      from random import randint                              xrow=raw_input("Enter the number of rows to be present in image.=>")      row=int(xrow)      ycolumn=raw_input("Enter the number of columns to be present in image.=>")      column=int(ycolumn)         A={}        for x in xrange(1,row):            for y in xrange(1,column):                a=randint(0,65535)                A[x,y]=a          imshow(A) 

But whenever i run this code, i get an error displaying "TypeError: Image data can not convert to float".Is there any solution for this.

I apologies for the mistakes in my write up, as this is my first question which i have asked above.

回答1:

This happened for me when I was trying to plot an imagePath, instead of the image itself. The fix was to load the image, and plotting it.

回答2:

This question comes up first in the Google search for this type error, but does not have a general answer about the cause of the error. The poster's unique problem was the use of an inappropriate object type as the main argument for plt.imshow(). A more general answer is that plt.imshow() wants an array of floats and if you don't specify a float, numpy, pandas, or whatever else, might infer a different data type somewhere along the line. You can avoid this by specifying a float for the dtype argument is the constructor of the object.

See the Numpy documentation here.

See the Pandas documentation here

Try this

>>> plt.imshow(im.reshape(im.shape[0], im.shape[1]), cmap=plt.cm.Greys) 

回答4:

From what I understand of the scikit-image docs (http://scikit-image.org/docs/dev/index.html), imshow() takes a ndarray as an argument, and not a dictionary:

http://scikit-image.org/docs/dev/api/skimage.io.html?highlight=imshow#skimage.io.imshow

Maybe if you post the whole stack trace, we could see that the TypeError comes somewhere deep from imshow().

try

import skimage import random from random import randint import numpy as np import matplotlib.pyplot as plt   xrow = raw_input("Enter the number of rows to be present in image.=>") row = int(xrow) ycolumn = raw_input("Enter the number of columns to be present in image.=>") column = int(ycolumn)  A = np.zeros((row,column)) for x in xrange(1, row):     for y in xrange(1, column):         a = randint(0, 65535)         A[x, y] = a  plt.imshow(A) plt.show()
