The ordinal 242 could not be located in the dynamic link library Anaconda3\Library\bin\mkl_intel_thread.dll

Question

I have just installed Anaconda 5.3 64-bit (Anaconda3-5.3.0-Windows-x86_64) on Windows 10 and am getting this error when trying to run Spyder.

pythonw.exe

Answer 1

This is not a proper answer, but for me (having the exact same problem) a workaround was to downgrade "anaconda" to 5.2.0 with the Anaconda Navigator. If that works for you, too, you could start upgrading individual packages to see when the error reappears. Maybe it is a bug in one of the packages, not a problem with our systems.

Edit: Here are some links to similar or related discussions:

• entry point mkl_blas_dgem2vu could not be located
• https://github.com/spyder-ide/spyder/issues/7357

More edit: It also helped me to find the following files in "C:\Windows\System32" and rename them (I just appended "_renamed" to the file name).

• mkl_core.dll
• mkl_def.dll
• mkl_intel_thread.dll

If I understand correctly, Python will use those instead of the ones in the Anaconda folder, which can cause problems.
