@YanyuanAI Could you refer to https://github.com/ethz-asl/gflags_catkin/issues/15 ? From your error log: ``` --- LOG END --- error: downloading 'https://github.com/pybind/pybind11/archive/v2.6.0.tar.gz' failed status_code: 1 status_string: "Unsupported protocol" log: --- LOG BEGIN ---...

Can we unzip the compressed file in python into a temp file and pass this temp file to C++? After processing, we can delete the temp file.

> Sounds good. ok, I will add it soon. Probably tomorrow.

@dueringa you have to change ``` CONFIG_BOOTCOMMAND="run mmc_elf_bootcmd" ``` to ``` CONFIG_BOOTCOMMAND="run bootcmd_bare_arm" ```

@oliwkowemango yes, you're right. You can see that it actually uses `_Reset` in the linker script: https://github.com/umanovskis/baremetal-arm/blob/4ce7973889bbc1d64299e4a87634f471137e3761/src/04_cenv/linkscript.ld#L3 https://github.com/umanovskis/baremetal-arm/blob/4ce7973889bbc1d64299e4a87634f471137e3761/src/04_cenv/linkscript.ld#L13-L15 https://github.com/umanovskis/baremetal-arm/blob/4ce7973889bbc1d64299e4a87634f471137e3761/src/04_cenv/startup.s#L6-L10

还是自己看代码，自己解决吧

> 大佬们解决了吗，我也遇到了这个问题 这个要修改 pnnx 的源代码. pnnx 目前不支持 把 aten::exp 转成 ncnn 中的 UnaryOp.

> 大佬们解决了吗，我也遇到了这个问题 你可以参考 https://github.com/csukuangfj/ncnn/pull/1 这个，添加对 `aten::exp` 的处理。 但是，可能在转换的过程中，你的模型里面，还有 pnnx 未支持的 op, 你自己还要再改 pnnx 的源代码.

有进展么
