I get the same error. @Iswarya05 how did you solve this problem? Do we need to built the tensorflow from source?

[fisakhan]

I solved this problem by installing TensorFlow C API from https://www.tensorflow.org/install/lang_c because tf.load_op_library requires libtensorflow_framework.so

but

now I get the following error: NotFoundError: ./renderer/rasterize_triangles_kernel.so: undefined symbol: _ZN10tensorflow15TensorShapeBaseINS_11TensorShapeEEC1EN4absl4SpanIKxEE

Hi Im also getting the same error, even if I set -D_GLIBCXX_USE_CXX11_ABI=1 . How to solve it?
