Problem with build_cython.py

[lupotto]

Hello,

First of all thank you for share this amazing code and repo.

I am having troubles with build_cython.py, when I compile I got the following error:

Traceback (most recent call last):
File "build_cython.py", line 20, in
from Cython.Build import cythonize
ImportError: No module named Cython.Build
Traceback (most recent call last):
File "/home/alupotto/PycharmProjects/c_mon/utils/boxes.py", line 54, in
import utils_cython.cython_bbox as cython_bbox
ImportError: No module named 'utils_cython.cython_bbox'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/alupotto/PycharmProjects/c_mon/cmon.py", line 10, in
from utils.preprocess_sample import preprocess_sample
File "/home/alupotto/PycharmProjects/c_mon/utils/preprocess_sample.py", line 5, in
from utils.multilevel_rois import add_multilevel_rois_for_test
File "/home/alupotto/PycharmProjects/c_mon/utils/multilevel_rois.py", line 16, in
import utils.boxes as box_utils
File "/home/alupotto/PycharmProjects/c_mon/utils/boxes.py", line 66, in
raise('--> utils_cython modules compilation failed')
TypeError: exceptions must derive from BaseException

I tried to dis comment other libraries of build_cython.py and it can't detect the others as well. It would be awesome if anybody can help me out.

Thank you,

Did you try conda install cython?

[lupotto]

yes I do

I tried to enter in my environment and import cython and Cython.Build and it worked.

Python 3.5.5 |Anaconda, Inc.| (default, Mar 12 2018, 23:12:44)
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

import cython
import Cython.Build

But in the project I get this error

I solved the problem in this way:

1. Changing the PYTHONPATH in my ./bashrc file.
2. After that, I had to compile Cython by myself running this command: python build_cython.py build_ext --inplace in /detectorch/lib/utils_cython

Right now I can do all the imports and the different steps but I have another problem that seems to be related to my GPU: error in BilinearSampler.updateOutput: no kernel image is available for execution on the device

Any suggestions on this matter?

Again, thank you for sharing this

Hi, it seems that this might be related with your GPU being too old.

Please see here and here.

I solved the issue changing the architecture of the make.sh
