python - opencv import failed in windows container (on Windows Server 2016) -


i run following container test opencv-python environment on windows server 2016.

docker run -i --rm python:2.7-windowsservercore

(the python:2.7-windowsservercore image official python image base on microsoft/windowsservercore)

and in interacive console, got opencv-python installed by:

pip install opencv-python

after finished, test opencv-python package by:

python -c "import cv2"

but got following error:

traceback (most recent call last): file "<string>", line 1, in <module> file "c:\python\lib\site-packages\cv2\__init__.py", line 9, in <module> .cv2 import * importerror: dll load failed: specified module not found.

then installed python-2.7.13 on host(not inside container), input same pip install commands, , test python -c "import cv2" again, won't report error. wonder if there dll files missing in container? package or software should install in container fix error?

based on the accepted answer question put money on not having required msvc runtime. assuming compiled visual studio 2015 runtime can downloaded visual c++ redistributable visual studio 2015

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
