I have the following array x:
x = np.array([[ 0. , 1. , 0.47351264, 2. ],
[ 2. , 3. , 0.65425345, 2. ],
[20. , 21. , 0.71297456, 2. ],
[22. , 23. , 0.6863126 , 2. ],
[24. , 25. , 0.67509844, 2. ],
[26. , 27. , 0.68440122, 2. ],
[28. , 29. , 0.68737942, 2. ],
[30. , 31. , 0.71718599, 2. ],
[32. , 33. , 0.73359071, 2. ],
[34. , 35. , 0.6795543 , 2. ],
[ 4. , 5. , 0.64574043, 2. ],
[ 6. , 7. , 0.63806522, 2. ],
[ 8. , 9. , 0.69928704, 2. ],
[10. , 11. , 0.6190996 , 2. ],
[12. , 13. , 0.68331497, 2. ],
[14. , 15. , 0.65097253, 2. ],
[16. , 17. , 0.6896147 , 2. ],
[18. , 19. , 0.61292212, 2. ],
[37. , 38. , 0.58519669, 4. ],
[47. , 48. , 0.65853573, 4. ],
[49. , 50. , 0.63965727, 4. ],
[51. , 52. , 0.64220952, 4. ],
[53. , 54. , 0.65616207, 4. ],
[39. , 40. , 0.70860266, 4. ],
[41. , 42. , 0.68387971, 4. ],
[43. , 44. , 0.69205266, 4. ],

[57. , 58. , 0.65458359, 8. ],
[59. , 60. , 0.70113174, 8. ],
[61. , 62. , 0.68490694, 8. ],
[63. , 36. , 0.66786758, 5. ],
[64. , 65. , 0.67181672, 16. ],
[66. , 67. , 0.68897615, 16. ],
[69. , 70. , 0.68773403, 32. ],
[71. , 68. , 0.6894432 , 37. ]])
And I tried to execute below:
np.array(map(tuple,x),dtype=[('i0',int),('i1',int), ('dist',float),('num',int)])
I am not entirely sure what is the above code trying to achieve. Can someone explain?
And I got the following error when I tried to execute the code:
*** TypeError: int() argument must be a string, a bytes-like object or a real number, not 'map'
