Error while executing the code

[wasimswdev]

I am using opencv version 3.4.1 and numpy 1.16.2 i have used a jpg file while executing the code i got the following error

File "C:\Users\Administrator\Anaconda3\lib\site-packages\numpy\lib\histograms.py", line 410, in _get_bin_edges
n_equal_bins = operator.index(bins)
TypeError: 'numpy.float64' object cannot be interpreted as an integer

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "1D Illuminant invariant image.py", line 58, in
(hist,waste)=np.histogram(temp,bins=nbins)

File "C:\Users\Administrator\Anaconda3\lib\site-packages\numpy\lib\histograms.py", line 780, in histogram
bin_edges, uniform_bins = _get_bin_edges(a, bins, range, weights)

File "C:\Users\Administrator\Anaconda3\lib\site-packages\numpy\lib\histograms.py", line 413, in _get_bin_edges
'bins must be an integer, a string, or an array')

TypeError: bins must be an integer, a string, or an array

Hi,

as you expected, the error occurs because of the numpy (and therefore also opencv) version.
There should be two ways to solve this issue:

1. Use a different numpy (& opencv) version. This can be done by:
   pip uninstall numpy
pip uninstall opencv-python
   and then get the proper older version:
   pip install opencv-python==3.1.0
   This automatically installs the right numpy version as well (1.11.1)
   Please use a virtualenv for all this.

2. Change line 57 in the code: nbins should be an integer, so i would recommend np.int here

I hope it helps and all the best!

You need to add np.int_() in this line also.

mX1sort2 = np.int_(np.divide(mX1sort, mX.shape[1]))

Dont't know if its logically correct.

Hi, the error is still the same did u all get the solution......

I've fixed it by adding a new row:
nbins=int(nbins)
between 57 and 58 lines of code.
