I noticed a memory leak when using imshow with the TkAgg backend (the Agg backend seems to be OK). Below is the system information and the result of running the memory leak script provided in the FAQ. I use Numeric for my work, but numarray is also installed. localhost:src$ python2.3 Python 2.3.4 (#1, Oct 31 2004, 10:10:53) [GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import numarray >>> numarray.__version__ '1.1' >>> import Numeric N>>> Numeric.__version__ '23.5' >>> import pylab >>> import matplotlib >>> matplotlib.__version__ '0.70.1' Output from memory leak checker script: 0 52632 17192 1 58484 18679 2 64180 20126 3 70000 21610 4 75772 23009 5 81564 24474 6 87272 25923 7 92988 27372 8 98684 28817 9 104456 30213 10 110160 31662 11 115956 33142 12 121764 34626 13 127468 36008 14 133172 37456 15 138968 38921 16 144748 40385 17 150444 41766 18 156132 43211 19 161816 44657 20 167516 46104 21 173204 47547 22 179008 48966 23 184676 50409 24 190372 51856 25 196060 53300 26 201764 54684 27 207536 56146 28 213240 57594 29 218948 59041 30 224616 60487 31 230288 61866 32 235964 63308 33 241664 64757 34 247444 66219 35 253248 67636 36 259024 69099 37 264712 70544 38 270408 71993 39 276084 73370 40 281780 74817 41 287568 76294 42 293260 77739 43 298960 79185 44 304648 80565 45 310352 82014 46 316100 83470 47 321792 84917 48 327452 86295 49 333236 87775 50 338928 89220 51 344728 90686 52 349444 92103 53 350840 93551 54 341692 95015 55 332648 96494 56 326660 97955 57 327812 99332 58 330168 100774 59 331612 102224 60 333080 103667 61 334524 105048 62 336444 106532 63 338144 107995 64 340060 109454 65 340968 110837 66 339636 112286 67 340340 113725 68 340984 115174 69 343468 116555 70 344244 118001 71 344456 119450 72 346036 120912 73 345808 122377 74 346944 123775 75 348400 125255 76 350128 126717 77 349552 128173 78 348952 129568 79 348036 131014 80 347556 132461 81 349000 133907 82 348828 135288 83 348528 136733 84 348156 138199 85 348420 139639 86 346460 141083 87 349312 142465 88 348832 143926 89 348404 145373 90 349888 146851 91 349780 148229 92 348632 149677 93 348748 151137 94 348040 152619 95 347016 154001 96 347108 155466 97 348496 156905 98 350300 158349 99 351956 159766 100 353368 161212 101 351320 162659 102 353216 164121 103 352952 165569 104 353652 166952 105 353256 168411 106 352088 169873 107 354428 171309 108 353440 172691 109 356004 174173 110 356008 175613 111 354096 177074 112 356036 178458 113 356228 179923 114 358000 181403 115 358012 182847 116 358220 184296 117 359524 185697 118 357732 187143 119 357580 188580 120 355680 190024 121 356336 191433 122 356676 192913 123 358288 194362 124 356352 195808 125 356684 197208 126 357296 198689 127 358940 200155 128 361464 201602 129 360752 203045 130 360148 204462 131 362032 205908 132 364036 207397 133 365656 208836 134 365360 210217 135 361592 211675 136 364828 213122 137 365600 214567 138 365184 215961 139 370880 217425 140 362380 218872 141 366444 220319 142 362832 221785 143 366424 223164 144 363908 224630 145 363980 226076 146 369004 227524 147 371348 228907 148 370072 230353 149 371484 231799 Average memory consumed per loop: 1427.6000k bytes Thanks! -- Jeff |
