Scipy installation on Window with mingw32
Hi, I am trying install to theano which also requires numpy and scipy on windows 7 with mingw32 compilers. I have successfully installed numpy using mingw32 but however when trying to install scipy I get this error: Looking for python27.dll Building msvcr library: "c:\python27\libs\libmsvcr90.a" (from C:\Windows\win sxs\amd64_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.21022.8_none_750b37ff97f4f68b\ msvcr90.dll) objdump.exe: C:\Windows\winsxs\amd64_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0 .21022.8_none_750b37ff97f4f68b\msvcr90.dll: File format not recognized Traceback (most recent call last): File "<string>", line 1, in <module> File "c:\users\22193\appdata\local\temp\pip-build-d3f_pb\scipy\setup.py", line 415, in <module> setup_package() File "c:\users\22193\appdata\local\temp\pip-build-d3f_pb\scipy\setup.py", line 411, in setup_package setup(**metadata) File "c:\python27\lib\site-packages\numpy\distutils\core.py", line 169, in setup return old_setup(**new_attr) File "c:\python27\lib\distutils\core.py", line 151, in setup dist.run_commands() File "c:\python27\lib\distutils\dist.py", line 953, in run_commands self.run_command(cmd) File "c:\python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run() File "c:\python27\lib\site-packages\numpy\distutils\command\install.py", l ine 62, in run r = self.setuptools_run() File "c:\python27\lib\site-packages\numpy\distutils\command\install.py", l ine 36, in setuptools_run return distutils_install.run(self) File "c:\python27\lib\distutils\command\install.py", line 563, in run self.run_command('build') File "c:\python27\lib\distutils\cmd.py", line 326, in run_command self.distribution.run_command(command) File "c:\python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run() File "c:\python27\lib\site-packages\numpy\distutils\command\build.py", lin e 47, in run old_build.run(self) File "c:\python27\lib\distutils\command\build.py", line 127, in run self.run_command(cmd_name) File "c:\python27\lib\distutils\cmd.py", line 326, in run_command self.distribution.run_command(command) File "c:\python27\lib\distutils\dist.py", line 972, in run_command cmd_obj.run() File "c:\python27\lib\site-packages\numpy\distutils\command\build_src.py", line 147, in run self.build_sources() File "c:\python27\lib\site-packages\numpy\distutils\command\build_src.py", line 164, in build_sources self.build_extension_sources(ext) File "c:\python27\lib\site-packages\numpy\distutils\command\build_src.py", line 323, in build_extension_sources sources = self.generate_sources(sources, ext) File "c:\python27\lib\site-packages\numpy\distutils\command\build_src.py", line 376, in generate_sources source = func(extension, build_dir) File "scipy\spatial\setup.py", line 35, in get_qhull_misc_config if config_cmd.check_func('open_memstream', decl=True, call=True): File "c:\python27\lib\site-packages\numpy\distutils\command\config.py", li ne 312, in check_func self._check_compiler() File "c:\python27\lib\site-packages\numpy\distutils\command\config.py", li ne 39, in _check_compiler old_config._check_compiler(self) File "c:\python27\lib\distutils\command\config.py", line 102, in _check_co mpiler dry_run=self.dry_run, force=1) File "c:\python27\lib\site-packages\numpy\distutils\ccompiler.py", line 59 6, in new_compiler compiler = klass(None, dry_run, force) File "c:\python27\lib\site-packages\numpy\distutils\mingw32ccompiler.py", line 96, in __init__ msvcr_success = build_msvcr_library() File "c:\python27\lib\site-packages\numpy\distutils\mingw32ccompiler.py", line 360, in build_msvcr_library generate_def(dll_file, def_file) File "c:\python27\lib\site-packages\numpy\distutils\mingw32ccompiler.py", line 274, in generate_def raise ValueError("Symbol table not found") ValueError: Symbol table not found ---------------------------------------- Command "c:\python27\python.exe -u -c "import setuptools, tokenize;__file__='c:\ \users\\22193\\appdata\\local\\temp\\pip-build-d3f_pb\\scipy\\setup.py';exec(com pile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __f ile__, 'exec'))" install --record c:\users\22193\appdata\local\temp\pip-wxyrfu-r ecord\install-record.txt --single-version-externally-managed --compile" failed w ith error code 1 in c:\users\22193\appdata\local\temp\pip-build-d3f_pb\scipy\ C:\Python27\Scripts> I realize this is due to some problem with resolving symbols in python27.dll. Is there a workaround for this? I need this to work on this setup as this is my workstation at office and I cannot install Ubuntu which would have been way easier. Things I have tried: I used to get an error while installing scipy for lapack/blas resources not found, I was able to get through by downloading and compiling them from source. I have tried to install scipy from http://www.lfd.uci.edu/~gohlke/pythonlibs/ and it does install scipy successfully but I get a 64-bit compatibility error when I try to import theano. Please help as I'm stuck here.

Hi, A few comments: - you really really want to use a scientific Python distribution to avoid these issues on Windows. see http://scipy.org/install.html - we used to build scipy .exe installers with mingw32 but don't do that anymore because it's just too much of a pain. IIRC the last release we did that for was 0.16.0, with the toolchain in https://github.com/numpy/numpy-vendor. - I don't recognize the error; looks not specific to recent changes in scipy so there's probably something in your environment not set up quite right.
