This page compiles a list of common errors that can appear when using Scipion.

Launching Eman boxer protocol

If you see an error like 'Cannot mix incompatible Qt library (version 0x40806) with this library (version 0x40804)'. This means the Qt installed on your computer is conflicting with the Qt distributed with EMAN2. In most cases it gets solved by removing the Qt that comes with EMAN2 from EMAN2DIR/extlib/lib.

Compiling Scipion with OpenCV

If you have problems compiling Scipion with OpenCV support (CUDA version >=6.5), e.g. opencv-2.4.9 compilation fails with an error:

Error: target 'software/lib/libopencv_core.so' not built (after running 'make install > /home/user/soft/scipion/software/log/opencv_make_install.log 2>&1')

And log file (software/log/opencv_make.log) shows something like:

[ 9%] Building NVCC (Device) object modules/core/CMakeFiles/cuda_compile.dir/src/cuda/cuda_compile_generated_gpu_mat.cu.o
/usr/include/string.h: In function ‘void* __mempcpy_inline(void, const void, size_t)’:
/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope
return (char *) memcpy (__dest, __src, __n) + __n;
^
CMake Error at cuda_compile_generated_gpu_mat.cu.o.cmake:264 (message):
Error generating file
/home/mag/opencv/build_opencv_master/modules/core/CMakeFiles/cuda_compile.dir/src/cuda/./cuda_compile_generated_gpu_mat.cu.o

Then:

  1. Find the micro-architecture name for your GPU card, e.g. Kepler for K40 or Fermi for M2070 card
  2. cd $SCIPION_HOME/software/tmp/opencv-2.4.9
  3. Run cmake -DCUDA_GENERATION=Kepler -DWITH_CUDA:BOOL=ON -DCMAKE_INSTALL_PREFIX:PATH=/path/to/scipion/software . > /path/to/scipion/software/log/opencv_cmake.log 2>&1 substituting correct path and micro-architecture
  4. Modify source files in opencv-2.4.9 folder according to this and this fix
  5. Re-run scipion install, opencv now should compile cleanly

Scipion freezes after click on open bibtex

This likely happens because your machine doesn't have a default program to open bibtex. Type this in your terminal to set gedit as your default program for bibtex files:

xdg-mime default gedit.desktop text/x-bibtex

Compiling Scipion in Opensuse

Scipion instalationin Opensuse sometimes involves a few drawbacks. Once in the terminal the compilation has been launched, ./scipion install, stop the installation (Crtl+C). It is neccesary to change the python version (download python 2.7.13). Copy the download file to scipion\software\tmp\ and edit next file scipion\software\install\script.py

The line in which the python version is specified must be modified by the downloaded version 2.7.13, it means to substitute the old version 2.7.8 by 2.7.13. Finally we can go to the terminal again and relaunch the installation by doing ./scipion install.

Endless list of CUDA related errors

Conditions

  • CUDA set to True (in config\scipion.conf)
  • Multiple CUDA versions are installed

Example

 /usr/local/cuda/include/crt/common_functions.h:64:0: warning: "__CUDACC_VER__" redefined #define __CUDACC_VER__ "__CUDACC_VER__ is no longer supported. Use __CUDACC_VER_MAJOR__, __CUDACC_VER_MINOR__, and __CUDACC_VER_BUILD__ instead." ^ <command-line>:0:0: note: this is the location of the previous definition

 /usr/local/cuda/include/device_atomic_functions.h(107): warning: missing return statement at end of non-void function "atomicAdd"

Cause

Version conflict while linking

Fix

make sure that all paths to *CUDA* and *NVCC* in config\scipion.conf are absolute

Requirement already satisfied

Conditions

  1. you had Scipion already installed (from source)
  2. later on you installed numpy again (e.g. with pandas)
  3. you want to reinstall Scipion (from source)

Example

Building numpy ...
python /home/user/Scipion/software/lib/python2.7/site-packages/pip install numpy==1.14.1
Requirement already satisfied: numpy==1.14.1 in /home/user/.local/lib/python2.7/site-packages
Error: target '/home/user/Scipion/software/lib/python2.7/site-packages/numpy' not built (after running 'python /home/user/Scipion/software/lib/python2.7/site-packages/pip install numpy==1.14.1')

Cause

Numpy version conflict?

Fix

uninstall Scipion's version of numpy

scipion run pip uninstall numpy
rm -rf software/lib/python2.7/site-packages/numpy

run install again

scipion install -j 8

ImportError: cannot import name HTTPSHandler

Example

Building pip ...
python scripts/get-pip.py -I --no-setuptools

    main()

ImportError: cannot import name HTTPSHandler
Error: target 'scipion/software/lib/python2.7/site-packages/pip' not built (after running 'python scripts/get-pip.py -I --no-setuptools')

Cause

Missing libssl-dev

Fix

sudo apt-get install libssl-dev
rm -rf software/bin/python* software/lib/python2.7/
./scipion install

Launching XMIPP CL2D protocol

If you have problems compiling Scipion with OpenCV support (CUDA version >=6.5), e.g. opencv-2.4.9 compilation fails with an error:
