PyCMS: ICC Profil CANNOT transform

Question

Now I have a project about color-management for the smartphone camera and i have a that I can't transform my selfmade icc profile in the pycms. It raises always the error 'PIL.ImageCms.PyCMSError: cannot build transform '. Now, i am very confused，when i use the standard icc profile, the transform is always successful.

Therefore, I consider that there are a problem either with my selfmade icc Profile or something wrong with the Codes. So i have made my ICC Profile for smartphone camera with 3 methods:

The first method: with software 'color checker camera calibration' Firstly, i have sampled all Pictures from differents smartphones. And then i have transformed the 'jpeg'pictures in 'Tiff' and lade them in the software. Finally, I get my icc Profile.

Second method with software 'I1 Profiler' and the third method with 'BaicColor input 6' are also similar as the first method.

But all of the Icc profile can’t be transformed in my code. Now i don't know where is the problem in my code or in my ICC profile. Could you please tell me where is my problem? on my ICC Profile OR on my code? the following is my code in Python3.7 and in hyperlinks you will also find my icc.enter link description here
