I'm using the PySpin api for a Point Grey camera in Anaconda. The api is a Python wrapper for a C++ library called Spinnaker (https://www.ptgrey.com/spinnaker-sdk).
When I import within Spyder (import PySpin), things work fine (note I start Spyder from the Conda prompt in the environment where everything is installed). Unfortunately running the import from the conda prompt instead of Spyder (python foo.py where foo.py contains import PySpin) yields:
Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.
The ordinal 242 could not be located in the dynamic link library C:\Anaconda3\Library\bin\mkl_intel_thread.dll
Note I installed Spinnaker (PySpin) from a wheel at the anaconda prompt:
pip install spinnaker_python-1.20.0.15-cp36-cp36m-win_amd64.whl
A bunch of places online it says to find the following files in C:\Windows\System32 and rename them or delete them:
mkl_core.dll
mkl_def.dll
mkl_intel_thread.dll
Those files are not present on my machine, so that seems to not be the problem in my case.
For instance here they mention that solution:
The ordinal 242 could not be located in the dynamic link library Anaconda3\Library\bin\mkl_intel_thread.dll
When I first import numpy and the import PySpin, then it works for me.
import numpy as np # must be imported first
import PySpin
system = PySpin.System.GetInstance()
version = system.GetLibraryVersion()
print('Library version: %d.%d.%d.%d' % (version.major, version.minor, version.type, version.build))
# Library version: 1.20.0.15
I am using Python 3.5 under Windows 10 with Miniconda.
