Errors with Train.py about hover_net HOT 18 CLOSED

I mean the virtual environment is fully set up with python 3.6..... however it seems to be initialising with 2.7 as you said. I'll try see how I can fix this.

Yeah - it seems one of the packages i installed manually through conda has simultaneously downgraded python. Will update.

Hi @luke2997

It seems that you have not put the GPU ids as a string. If using GPUs 0 and 1, use:

python train.py --gpu='0,1'

Please let us know if this fixes the issue.

from hover_net.

@simongraham - this doesn't fix the problem unfortunately.

from hover_net.

Can you let me know what tensorpack version you are using and then copy the command that you use in the terminal.

from hover_net.

I have both tensorFlow v1.12 and tensorpack 0.9.0.1. In the command I type:

python train.py --gpu='0,1'

I also get the below output file, not sure if related.

from hover_net.

The output is telling you that there is already a checkpoint file where you plan to save your logs. You need to press k (keep), d (delete) or q (quit) depending on what you want to do.

I'm still not sure exactly what you are requesting here? Are you getting an error? If so, please supply the terminal output.

from hover_net.

Yeah i did delete it, i think I now realise the source of the issue being a couple of modules are not importing properly due to libpng12 ... i'll update when I get this resolved.

from hover_net.

I will close this issue for now. Please reopen if necessary, with a specific question- then we can be of more assistance.

from hover_net.

Please reopen: I had to start all over again as there were issues with my venv. Extract_patches.py worked before but when I run it now I get the below code.. is it something to do with the dataset?

from hover_net.

@luke2997 , for the record, you can reopen it by yourself.
Please show me

Also, please provide as many details as possible for what you have changed in the code compared to the github version.

from hover_net.

Well I only changed the paths which is why I didn't understand why the error came. So I have the same lines as those above.

I had a look and tried running config.py and it seems I get an error related to #12 (comment). So it seems it is an error with my paths, although it's the same paths i used before which then worked!

One thing that may be causing it is when i first run the code I get this error:

/lib64/libstdc++.so.6: version CXXABI_1.3.9' not found`

And I export it using

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/*username*/.conda/envs/*VirtualEnvironment*/lib/

which then fixes it but causes the error above.

from hover_net.

That is very strange, may be your new environment broke something. For now, you can try change this

into return flag, int(last_step) to enforce all input to range is int.

from hover_net.

Also, the preferred library version is listed here https://github.com/vqdang/hover_net/blob/master/requirements.txt

So you may want to check if it matched. In case you need to reinstall, use the following as guideline.

conda create --name test python=3.6
conda activate test
pip install opencv-python=3.2 scipy scikit-image pandas matplotlib
pip install --upgrade git+https://github.com/tensorpack/[email protected]
pip install --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.12.0-cp36-cp36m-linux_x86_64.whl
source activate test

from hover_net.

Perfect thanks a lot! Changing that line of code fixed it and I was able to successfully extract patches. However, I have a few errors with train.py suggesting TF GPU is not working, so I will try create a new virtual environment as you suggested and try again, anyway as perhaps there was a fault using tensorflow gpu. Although it is a bit of a pain getting these packages installed all together for some reason.

Hi @luke2997 ,

As @vqdang suggested- please setup your environment from scratch to ensure there are no issues with library versions.

Although it is a bit of a pain getting these packages installed all together for some reason.

Installing the libraries should be simple and easy enough if you follows @vqdang 's instructions. This is only a few lines in the terminal. Of course you need to make sure you run the commands separately- line by line.

After this has been done let us know and we can advise how to proceed. Whaat CUDA version do you have installed?

from hover_net.

I'm in Mainland China so some channels get blocked, e.g. using the command above doesn't work for tensorflow, but anyway I do have all the requirements I believe and I have restarted and now got a little further, I assume GPU is working now! However I do have an output but get the long below error. Also I have Cudatoolkit 9.2 and cudnn 7.6.5.

It looks like you are using python 2.7. As stated in the requirements you need to use python 3.6.

Right, thanks a lot for the help I appreciate it, I've successfully trained the data after changing the Python Version!
