cnn.predict error #16

Closed pjstanley1 closed 3 years ago

pjstanley1 commented 3 years ago

Hello Adına,

I've encountered an error when trying to run cnn.predict. The issue appears to arise from the dtype of the time array not being a format np.isnan likes. Any suggestions on how to fix this issue would be much appreciated! The error is as follows:

TypeError Traceback (most recent call last)

in ----> 1 cnn.predict(modelname=MODELS[0], 2 times=lc.time, 3 fluxes=lc.flux, 4 errs=lc.flux_err) 5 single_pred = cnn.predictions[0] ~/anaconda3/envs/stella/lib/python3.8/site-packages/stella/neural_network.py in predict(self, modelname, times, fluxes, errs, multi_models, injected) 541 err = errs[j] + 0.0 542 --> 543 q = ( (np.isnan(time) == False) & (np.isnan(lc) == False)) 544 time, lc, err = time[q], lc[q], err[q] 545 TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe'' Thanks, Patrick

Hi there! This is a test of github actions.

Hello, I managed to fix the error by changing line 539 of neural_network.py from: time=times[j] + 0.0 to time=times[j].bkjd +0.0
