AttributeError when import tvm.relay

Troubleshooting
#1

Hi,

I guess this is related to some recent commits, so I will trace back some older version that works. But for reference, after pulling the repo a few minutes ago, this error appears when I run the tutorial that converts an ONNX model:

Traceback (most recent call last):
  File "01_from_onnx.py", line 50, in <module>

Hi, did you fix the error?

#3

Did you recompile tvm?

#4

Yes, everything works after recompiling. Sorry if I did not update the post.

@SerenaC94 @hgt312 I am getting the same error whiile trying to use main branch on top of Xilinx EDGE device. Tried recompiling and reinstalling. didnt help - any suggestion?

@SerenaC94 @hgt312 I just followed the steps mentioned here - Vitis-AI Integration — tvm 0.8.dev0 documentation

Tried with v0.7.0 branch too. Pops the same error.

root@pynq:/home/xilinx/tvm/python# python3 -c 'from tvm import relay'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/xilinx/tvm/python/tvm/relay/__init__.py", line 23, in <module>

  File "/home/xilinx/tvm/python/tvm/relay/ty.py", line 26, in <module>
Any = _ffi_api.Any
AttributeError: module 'tvm.relay._ffi_api' has no attribute 'Any'

Then I noticed that “Any” variable is not used anywhere in the file (other than this creating/assigning instance) - /home/xilinx/tvm/python/tvm/relay/ty.py - Commented this line and tried to do “python3 -c ‘from tvm import relay’” but throws another error:

    self.__init_handle_by_constructor__(_ffi_transform_api.PassInfo, opt_level, name, required)
AttributeError: module 'tvm.ir._ffi_transform_api' has no attribute 'PassInfo'

Any suggestions?

Hello! In the process of building TVM0.8, I also met the same problem. Could you please tell me how to solve it? Thanks!

#8

Please try to build the tvm from scratch and reinstall the python binding(if you used the setup.py)

#9

Thank you very much. It has been successfully installed a week ago through “install from source”.I am a senior student. I used to do the development related to Xilinx FPGA, but I found it very difficult to learn it recently.Many functions have changed in version 0.8, and it’s a bit hard to find the exact functions used in the 0.6 code online.Can I still find the Tutorial for 0.6dev?Thanks！

I build on xilinx vck190 follow Vitis AI Integration — tvm 0.10.dev0 documentation, but error of

and I rebuild tvm_runtime again and again, but failed.

Any one can help me.
