Theano: Import error under Windows: lazylinker_c.c

[gsmafra]

Hello

I've had the following error when trying to import theano over Windows 7 64 bits, Anaconda, Python 2.7, using Spyder. I installed the library using the pip pull with no problems

The C code seems to be the file lazylinker_c.c

I already installed and succesfully imported theano in another machine with similar configurations and had no problems at all

Obs: I am new to Python

Update 2: I think my compiler was too old, replaced by 4.9.2

I have lots of text in the error but the important part seems to be this one:

I already tried to do the cxxflags march trick but it doesn't work

Same issue/errors.
After printing that out, the error message changes to one involving gof (when I try importing again in the same python session).
Windows 7.1 , 64 Bit, Anaconda. Tried installing bleeding edge Theano as well as (seperately) the pip version.

[abergeron]

The cmd screenshot you posted conviniently truncates all error messages after the first two characters, therefore I can't say anything. My guess however is that you have the same error are the OP, which is that the gcc version you installed does not support 64-bits (like the very first error message seems to indicate:

C:\Users\Gustavo\AppData\Local\Theano\compiledir_Windows-7-6.1.7601-SP1-Intel64_Family_6_Model_42_Stepping_7_GenuineIntel-2.7.9-64\lazylinker_ext\mod.cpp:1: sorry, unimplemented: 64-bit mode not compiled in

Get a build of gcc that supports 64-bit and try again.

[gsmafra]

Thank you, abergeron, but I had already realized that, see my "Update 2". New message doesn't present anything like that ("sorry, unimplemented: 64-bit mode not compiled")

[abergeron]

The Update 2 does not contain the full error output so I can't say anything about it.

[gsmafra]

Too big to paste directly here

[abergeron]

The very first error indicates that you have problems with your environnement. Fix those, and if you still have problems with theano then, we'll look at it.

C:\Users\Gustavo\Anaconda\include/pyport.h:886:2: error: #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."
 #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."

[gsmafra]

I replaced my compiler by the one recommended in the install section
(http://deeplearning.net/software/theano/install_windows.html)

Now I have this

http://m.uploadedit.com/ba3c/1428860353377.txt

I wasn't able to find the "openmp support option" though

Just to be sure, if I don't need CUDA right now then I don't need to follow the "Visual Studio and CUDA" steps in the same install section right?

Solved: installed libpython

[nouiz]

Thanks for the info, this was also needed for anaconda instruction that is
updated there:

https://github.com/Theano/Theano/pull/2764

One error you had was hiding something else. That PR fix that problem too.

For Anaconda user install theano from: conda install theano pygpu

[deaspo]

Followed and installed for Anaconda and now am getting the error: "RuntimeError: To use MKL 2018 with Theano you MUST set "MKL_THREADING_LAYER=GNU" in your environement.". Followed the instruction from here. Didn't solve my problem, so I downgraded to 2017 version, conda install mkl=2017.

Now I can run Theano without problems
