alexwong opened a new issue #5835: URL: https://github.com/apache/incubator-tvm/issues/5835
I recently tried to run the darknet tutorial using a shared library built from the master branch (https://github.com/pjreddie/darknet) rather than the one hosted here https://github.com/dmlc/web-data/tree/master/darknet/lib which seems to be https://github.com/siju-samuel/darknet/tree/tvm. I am hitting an error in the darknet->relay converter. ``` Traceback (most recent call last): File "tutorials/frontend/from_darknet.py", line 92, in <module> mod, params = relay.frontend.from_darknet(net, dtype=dtype, shape=data.shape) File "/tvm/python/tvm/relay/frontend/darknet.py", line 851, in from_darknet return GraphProto(net, shape, dtype).from_darknet() File "/tvm/python/tvm/relay/frontend/darknet.py", line 815, in from_darknet params = self._get_darknet_params(self._net.layers[i], prefix) File "/tvm/python/tvm/relay/frontend/darknet.py", line 664, in _get_darknet_params params = self._get_convolution_weights(layer, opname) File "/tvm/python/tvm/relay/frontend/darknet.py", line 470, in _get_convolution_weights biases = self._read_memory_buffer((layer.n, ), layer.biases) File "/tvm/python/tvm/relay/frontend/darknet.py", line 455, in _read_memory_buffer data_np[i] = data[i] RuntimeError: cannot dereference null pointer from cdata 'float *' ``` Using either the .so hosted by TVM or building https://github.com/siju-samuel/darknet/tree/tvm works fine. I am wondering if this is a version problem between the master darknet branch and the one TVM is testing against (although, it seems the one TVM is using isn't that stale). If so, I am also wondering if/when the converter and library used by TVM for testing will be updated to the master version? @siju-samuel ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
