Hi，thank you for your great work！ when I run tf.load_op_library('dirt/librasterise.so'),it has error: Traceback (most recent call last): File "", line 1, in File "/home/lj/software/anaconda3/envs/MGN_py2.7/lib/python2.7/site-packages/tensorflow/python/framework/load_library.py", line 60, in load_op_library lib_handle = py_tf.TF_LoadLibrary(library_filename) tensorflow.python.framework.errors_impl.NotFoundError: ../dirt/librasterise.so: undefined symbol: eglCreateContext

how can I solve these problem?

There should be a libEGL linked, not just libEGL_nvidia. Did you have to override any paths/etc. in the build? It should pick up libEGL automatically, and that then calls into libEGL_nvidia

I am facing similar issue but getting this error

tf.load_op_library('dirt/librasterise.so') Traceback (most recent call last): File "", line 1, in File "/home/ubuntu/anaconda3/envs/mgn4/lib/python3.7/site-packages/tensorflow/python/framework/load_library.py", line 61, in load_op_library lib_handle = py_tf.TF_LoadLibrary(library_filename) tensorflow.python.framework.errors_impl.NotFoundError: /usr/lib/x86_64-linux-gnu/libOpenGL.so.0: undefined symbol: _glapi_tls_Current

@pmh47 please advise

Thank you for your quick reply! In my system it can't find EGL library automatically, so I edit CMakeCache.txt. Now I change EGL_LIBRARIES:FILEPATH=/usr/lib64/libEGL.so.1, it can be build successfully, but when I ran python tests/square_test.py, another error shows: 2021-09-06 16:28:41.482959: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 AVX512F FMA 2021-09-06 16:28:41.774868: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1432] Found device 0 with properties: name: Tesla V100-PCIE-32GB major: 7 minor: 0 memoryClockRate(GHz): 1.38 pciBusID: 0000:63:00.0 totalMemory: 31.75GiB freeMemory: 31.45GiB 2021-09-06 16:28:41.994806: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1432] Found device 1 with properties: name: Tesla V100-PCIE-32GB major: 7 minor: 0 memoryClockRate(GHz): 1.38 pciBusID: 0000:64:00.0 totalMemory: 31.75GiB freeMemory: 29.94GiB 2021-09-06 16:28:42.000071: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1511] Adding visible gpu devices: 0, 1 2021-09-06 16:28:42.880030: I tensorflow/core/common_runtime/gpu/gpu_device.cc:982] Device interconnect StreamExecutor with strength 1 edge matrix: 2021-09-06 16:28:42.880124: I tensorflow/core/common_runtime/gpu/gpu_device.cc:988] 0 1 2021-09-06 16:28:42.880138: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1001] 0: N Y 2021-09-06 16:28:42.880146: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1001] 1: Y N 2021-09-06 16:28:42.880328: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1115] Created TensorFlow device (/job:localhost/replica:0/task:0/device:GPU:0 with 30511 MB memory) -> physical GPU (device: 0, name: Tesla V100-PCIE-32GB, pci bus id: 0000:63:00.0, compute capability: 7.0) 2021-09-06 16:28:42.880730: I tensorflow/core/common_runtime/gpu/gpu_device.cc:1115] Created TensorFlow device (/job:localhost/replica:0/task:0/device:GPU:1 with 29049 MB memory) -> physical GPU (device: 1, name: Tesla V100-PCIE-32GB, pci bus id: 0000:64:00.0, compute capability: 7.0) 2021-09-06 16:28:43.528035: F /home/lj/code/3D/clothing/software/dirt/csrc/gl_common.h:46] extensions eglQueryDevicesEXT, eglQueryDeviceAttribEXT and eglGetPlatformDisplayEXT not available

@ljiqy did you solve it ? I have same error like you
