ERROR Makefile:123 OpenBLAS: Detecting CPU failed. Please set TARGET explicitly, e.g. make TARGET=your_cpu_target

[typxxi]

I have a up to date WIN 10 system with
VM Player 12 running on an INTEL 4 CORE CPU N3520

With both iso of ubuntu 12 and mint 18 I got that sam ERROR 123 while installing torch 7 ....

First I thougt it was a torch problem and in the torch readme was nothing to be found about 123 error

Then I found a reference here in the issues with a solution using the version 0.2.9.rc2

But that regards a mac pro problem and I have windows 10 and Intel CPU.
Tested it on 2 machines with both ISO Files.

How can I set that CPU Target to what value?

Thanks a lot

N3520 appears to belong to the "Bay Trail" core series of "ATOM" type CPU, so please try building with "make TARGET=ATOM".
If you could post the output of "cat /proc/cpuinfo" from your VM (or at least the "cpu family" and "model" numbers from it) the relevant data could be added to the cpu detection code of the OpenBLAS build system. (Though with a VM it is also possible that the virtual machine does not receive all cpu features of the actual hardware, which might mislead the build system even if it "knows" that type of cpu already)

sorry, had a problem cause first I thought that "cat/proc/cpuinfo" would mean a path I could not find but than I copied the string and while inserting I recogniced the "SPACE" and that this is a COMMAND

Sorry, but I am completly "Linux" blind / newbie and I just can imagine that your
"make TARGET=ATOM"
should be a parameter , but I am just aware of what I have to do to install torch7 by this

git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
./install.sh

I think the error occured by the last step so it might be necessary to change the last script / batchfile install.sh

[typxxi]

Here is what I found in the torch install.sh regarding openblas

*if [[ uname == 'Linux' ]]; then
export CMAKE_LIBRARY_PATH=/opt/OpenBLAS/include:/opt/OpenBLAS/lib:$CMAKE_LI$
fi
export CMAKE_PREFIX_PATH=$PREFIX
*

That maybe environment variable $prefix is a few line later used here with a make command

cmake .. -DCMAKE_INSTALL_PREFIX="${PREFIX}" -DCMAKE_BUILD_TYPE=Release -DWITH$$
(make 2>&1 >>$PREFIX/install.log || exit 1) && (make install 2>&1 >>$PREFIX/in$_

I hope that might help to find a workaround.

I just want to try to cholorize 100 year old photographs with this
https://github.com/satoshiiizuka/siggraph2016_colorization

and therefore I learned to install vmware player,
download ubuntu ISO and after first failure mint
install git
and then to install torch and more dependencies
and that OPENBAS is a part of torch installation

only to finally start torch and siggraph to get colored pics from the world exhibition chicago 1892

Long journey till now - at least for me

Thanks

NO, it happened earlier while executing

bash install-deps

#!/usr/bin/env bash
set -e

Alright then, try adding the "TARGET=ATOM" to the end of the line
make NO_AFFINITY=1 USE_OPENMP=1
in the install_openblas() function (top of first script you posted) and rerun the whole thing...

[typxxi]

Hey,

I edited the install-deps FILE here in the last line

install_openblas() {
    # Get and build OpenBlas (Torch is much better with a decent Blas)
    cd /tmp/
    rm -rf OpenBLAS
    git clone https://github.com/xianyi/OpenBLAS.git
    cd OpenBLAS
    if [ $(getconf _NPROCESSORS_ONLN) == 1 ]; then
        make NO_AFFINITY=1 USE_OPENMP=0 USE_THREAD=0
    else
#       make NO_AFFINITY=1 USE_OPENMP=1
        make NO_AFFINITY=1 USE_OPENMP=1 "TARGET=ATOM"

BUT: I still got the same error

Or do I have to remove the quotations to TARGET=ATOM?

[martin-frbg]

Yes, sorry for that - no quotation marks around the TARGET=ATOM
Also best add it to the make options in the other branch of the "if" as well, as long as we cannot be sure what the _NPROCESSORS_ONLN value is (I'd guess it to be the number of cpu cores, but if it is 1 for
the single cpu any changes in the "else" branch would be ignored).
If you still get the error after that, try with TARGET=NEHALEM

[typxxi]

Sorry, even with no quotation marks I still got the same error

Just checked it line by line - error is still the same

[typxxi]

In that function there is question for processors = 1

So I was wondering why I have to put that "Arguments" not into the first option

cause I remembered that the ubuntu settings in my VM Player were 1
So I looked there again under Menu
#1 PLAYER
#2 MANAGE
#3 VIRTUAL MACHINE SETTINGS

There I found
MEMORY: 2 GB
PROCESSORS: 1
.......

If I click on processor then I get more information like

Number of cores 1

I did not change anything here - it's just the ubuntu iso image I downloaded.

If TARGET=ATOM shall work in my environment doesn't the TARGET=ATOM in the 2 line here for processors = 1 ?

    if [ $(getconf _NPROCESSORS_ONLN) == 1 ]; then
        make NO_AFFINITY=1 USE_OPENMP=0 USE_THREAD=0 TARGET=ATOM
    else
#       make NO_AFFINITY=1 USE_OPENMP=1
        make NO_AFFINITY=1 USE_OPENMP=1 TARGET=ATOM

Shall I try that?
I don't want to mix things and codes... while dicussing

[typxxi]

Now the system is still running but I see a lot of messages I did not see before.

Seems to me that the script is using the first line after if and not the ELSE

   if [ $(getconf _NPROCESSORS_ONLN) == 1 ]; then
        make NO_AFFINITY=1 USE_OPENMP=0 USE_THREAD=0 TARGET=ATOM

Maybe I have to move the TARGET=ATOM in the line ?

[typxxi]

I canceled the previous run .
during the next run I canceled while crossing the former "error barrier"

Right now it is running again and I will let it run through .... and see what happens

many lines of this are still running - just marked while still running , then copy ... to paste it here.

[martin-frbg]

Yep. Did not really think through about the implications of the VM, i.e. that you might have just one core assigned to it, and only edited what I wrote earlier instead of creating a new message so you probably did not see it in time. Think it will run to completion now that you found out yourself what needed to be changed. (I'll see if I get around to creating a patch to recognize intel cpu code 55 - 37 in hexadecimal meaning extended model 3, model 7 - similar to 52eba81 )

[typxxi]

I got tons of lines on the screens - some warnings ... it is running and running

BUT: Is it really only a question of cores that if

if [ $(getconf _NPROCESSORS_ONLN) == 1 ]; then

Then I will change my ubuntu settings from 1 core to 2 cores and see what will happen - maybe / hopefully without all these warnings

[martin-frbg]

The tons of lines of output are harmless - OpenBLAS is quite a big library and this is mostly just the normal feedback from compiling each of the many source files. You may get an occasional warning about some unused local variable, and towards the end of the build process it will also build and run some automated tests to check its accuracy, but as long as it does not terminate with an error message everything should be alright.

[typxxi]

Hey,

finally I stopped the 1 processor virtual ubuntu machine and started a new run as 2 processor machine

That is still running ...
The vm player ubuntu system settings regarding processor always means CORES.
After I changed the core to 2 the VM Player displays now 2 PROCESSORS.

Let's wait and see ... at least much better than the last 2 or 3 days regarding progress and feelings.

[typxxi]

DID IT

but what does this mean - appeared shortly before the end

  Library Name     ... libopenblas_atom-r0.2.20.dev.a (Single threaded)  
To install the library, you can run "make PREFIX=/path/to/your/installation install".

[martin-frbg]

Seems the build went through correctly (the "make install" step is a few lines below the one we edited and will probably not have generated any output except perhaps asking for the system password), but the script still recognized only a single core. Depending on what torch and/or that siggraph code does, a single-threaded openblas may actually be all you need.
If you want to try a multithreaded version for comparison, you could edit that "if" block so that it has the USE_OPENMP=1 USE_THREAD=1 in both cases.
