Either let the installer add to your PATH - it adds multiple entries (worst option) or use Anaconda Prompt or Anaconda Navigator to launch the software or else use conda's activate script.

Thanks. But that is what the anaconda installer has added to the PATH. I tried with Anaconda Prompt and Navigator but the still have the problem.

Ah ok. Your problem is likely then non system DLLs in the system32 folder.

Some audio application installs them there, possibly some other software does too. I asked the audio people to stop, they didn't reply. They probably only care that their stuff runs correctly and have no concern about breaking people's systems.

Look for mkl DLLs in C:\Windows\System32.

Also please look at old bug reports before posting duplicates. In particular make sure to check closed issues.

Thanks again. In fact there are several files with the same name "mkl_intel_thread.dll" in other folders not in system32. I have renamed them to .bak but I still have the same problem.

@mingwandroid

from a normal cmd.exe prompt, and also from the Anaconda Prompt please type where mkl_intel_thread.dll and show the results of each.

On normal cmd.exe say
C:\Windows\System32\where.exe
C:\Windows\System32\mkl_intel_thread.dll
C:\Users\augus\Anaconda3\Library\bin\mkl_intel_thread.dll
and on Anaconda prompt
C:\Users\augus\Anaconda3\Library\bin\mkl_intel_thread.dll
C:\Windows\System32\mkl_intel_thread.dll

mkl 2019.0 intel_117 intel

Oh, you are mixing defaults with intel? Don't do that.

That really shouldn't be a problem. Especially on Windows, I believe Intel uses essentially identical build processes as us. Our MKL packages are just straight repacks of the intel packages.

@mingwandroid

The error message suggests an incompatibility, likely to do with version constraints across channels?

Once my Windows VM finishes downloading I'll take a look. Has taken about 4 hours so far!

I agree completely, I'm just confounded on what the conflict is. A conflict between defaults and intel is not impossible, but I don't think it's likely, either.

@mingwandroid

But looking again we see in your very first comment.

and i don't have the file " mkl_intel_thread.dll" on my system32 directory

But you then posted the result of where mkl_intel_thread.dll
C:\Windows\System32\mkl_intel_thread.dll

This is you problem, only MS should put DLLs in C:\Windows\System32, no one else should as it risks breaking your other software.

Sorry it took so long to track down!

I downgrade to anaconda 5.2 with python 3.6 and all works fine, the problem is with python 3.7 or mkl conda files.

Though it may seem that newer anaconda is the root cause, we are certain from our testing that our files are self consistent and working. You definitely have a conflict with something else on your system. Apparently that something else was compatible with the 5.2.0 release. What happens if you start with your 5.2.0 installation and then update numpy to version 1.15.3? I expect it will break in the same way that you see problems with anaconda 5.3.0 , but if you could help me test that theory, it would be helpful.
