Hi, I have a poolseq data set that I would like to analyze. However, even with the training data set I encounter the same error message

findfont: Font family ['serif'] not found. Falling back to DejaVu Sans.
The program nevertheless continues, but can these outputs be taken serious given the errors above?

Hi @klucek,
I haven't had found that the tensorflow error Error occurred when finalizing GeneratorDataset iterator: Cancelled: Operation was cancelled
changes the results, but I'm not sure about the ^H^H
s.
Can you check to see if a file named ./networks/testResults.pdf
was created? If so, then you should be able to see a plot of the training history on the bottom, and the predictions on the test set on the top. Provided those look normal, and the model and weights were created (./networks/model.json
& ./networks/weights.h5
), you should be able to ignore the above errors.
I'm hoping that these error messages will be resolved when I'm able to move to an updated tensorflow version.

I added optional muti-threading to model.fit for training on pool-seq data. Multi-threading can be disabled by simply using the default option for --nCPU
in ReLERNN_TRAIN
and ReLERNN_TRAIN_POOL
. Everything seems to be working using tensorflow 2.2, which is now the supported version via the README. I'm going to go ahead and close this issue now.
