It is difficult to debug your issue without more information. In my experience the biggest difficulty tends to be that of insufficient memory. Openslide by default keeps a cache for every opened slide. It is possible to modify openslide's source code to not create this cache. Then again your problem may be different.
So, this could be related to this previous issue, right?
Hi again, I am trying to install openslide from here in order to disable cache. However, I am not able to use it with Python and I am not sure how to force python to use this specific version of openslide. I know this is a bit out of the issue but, could you specify how did you manage to use it? Thanks :-)
What I did is download the source code for openslide. Then made a very minor change to the source code: https://github.com/openslide/openslide/blob/master/src/openslide.c comment line 347, uncomment line 348 Then I installed openslide manually and linked the PATH, LD_LIBRARY_PATH and LIBRARY_PATH environmental variables appropriately. Then if you install openslide-python it should work. You can even check from within python which library is used when loading openslide.
Thanks! This solve the memory issue. Checking the %RAM used per worker, this change reduce the requirements to half. If anyone face similar problem I have to mention that I could not make it run in a conda
environment.
Hi, I have just try to start with some learning and the
MIL_train.py
script fails with the title error. Searching a bit I found that seems to be related withmultiprocess
. If I set the--workers
to 0 the error is not longer there. However, the learning time increases a lot. I guess is something related with openslide but I am not able to find anything related to how it handles multiprocessing.Do you have any hints on this? Thanks
