malloc assertion failed #9

Closed AlexandruMoraru310 closed 4 years ago

Hello,

I tried to run some scripts in the examples/ct_reconstruction folder. I tried example_parallel_2d.py, example_fan_2d.py and example_fan_2d_shortscan.py. All of them give runtime error at the line:

sinogram = parallel_projection2d(phantom, geometry)

The error is:

python: malloc.c:2385: sysmalloc: Assertion (old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0) failed.

Any idea for a workaround?

Could you check which Tensorflow version you have currently installed? I stumbled across a possible problem with TensorFlow 2.2 today. Could you check if the problem is solved when you use Tensorflow 2.1 instead of 2.2?

With TensorFlow version 2.1 everything works just fine. Thank you!
