Hello!
I am currently trying to optimize a network running on rk3399 on a mali gpu and use current version of TVM( 0.7dev1 ). I followed the simple [tutorial](https://docs.tvm.ai/tutorials/autotvm/tune_relay_mobile_gpu.html) provided by the auto tuning tutorial and I am having problems. TVM does not seem to generate proper OpenCL code when generate opencl code for mali. If you look at the log below, it seems that a problem occurs because an invalid identifier('\n') is inserted in the current opencl code. > TVMError: OpenCL build error for device=0x7f8b2d07f0<source>:1:130: error: > expected \')\'\n__kernel void default_function_kernel1(__global float* > restrict conv, __global float* restrict data_vec, __global void* restrict > kernel) {\n > > ^\n\n<source>:1:39: note: to match this \'(\'\n__kernel void > default_function_kernel1(__global float* restrict conv, __global float* > restrict data_vec, __global void* restrict kernel) {\n > ^\n\n<source>:1:130: error: parameter name omitted\n__kernel > void default_function_kernel1(__global float* restrict conv, __global float* > restrict data_vec, __global void* restrict kernel) {\n > > ^\n\n<source>:7:401: error: expected expression\n > conv[(((((((int)get_group_id(2)) * 3136) + (((int)get_local_id(2)) * 196)) > + (((int)get_group_id(1)) * 28)) + (((int)get_group_id(0)) * 4)))] = > (conv[(((((((int)get_group_id(2)) * 3136) + (((int)get_local_id(2)) * 196)) + > (((int)get_group_id(1)) * 28)) + (((int)get_group_id(0)) * 4)))] + > (data_vec[((((((int)get_group_id(1)) * 1792) + (((int)get_group_id(0)) * > 256)) + ci))] * ((__global float*)kernel)[((((((int)get_group_id(2)) * 16384) > + (((int)get_local_id(2)) * 1024)) + (ci * 4)))]));\n > > > > > > ^\n\n<source>:8:413: error: expected expression\n > conv[((((((((int)get_group_id(2)) * 3136) + (((int)get_local_id(2)) * 196)) + > (((int)get_group_id(1)) * 28)) + (((int)get_group_id(0)) * 4)) + 1))] = > (conv[((((((((int)get_group_id(2)) * 3136) + (((int)get_local_id(2)) * 196)) > + (((int)get_group_id(1)) * 28)) + (((int)get_group_id(0)) * 4)) + 1))] + > (data_vec[((((((int)get_group_id(1)) * 1792) + (((int)get_group_id(0)) * > 256)) + ci))] * ((__global float*)kernel)[(((((((int)get_group_id(2)) * > 16384) + (((int)get_local_id(2)) * 1024)) + (ci * 4)) + 1))]));\n Looking at the above log, it seems that the OpenCL code is not working properly because "\n" is continuously inserted. I think the problem is in the part of generating opencl code in TVM rather than in the device. Could you please provide a solution for that part? --- [Visit Topic](https://discuss.tvm.ai/t/issue-of-auto-tuning-mali-gpu-auto-tuning-is-not-working-properly/6927/1) to respond.
