Missed call to write_output although had included it

 Hi, after developing my strategy, store it in "weights", I have included the following cell before submitting : import qnt.output as qnout 
 weights = weights.sel(time=slice("2005-01-01",None))
 qnout.check(weights, data, "stocks_nasdaq100")
 qnout.write(weights) # to participate in the competitionBut I got missed call to write output filter. Can you help me check my strategy with the id: ndl01 16718690Thanks,

 @multi_byte-wildebeest said in Missed call to write_output although had included it: 16718690 Hello. I have encountered a similar issue sometimes. Try saving the weights in a separate cell. qnout.write(weights) # to participate in the competitionIf that doesn't help, run the precheck https://github.com/quantiacs/toolbox/blob/main/qnt/precheck.ipynb.

 @multi_byte-wildebeest Dear multi_byte-wildebeest, 
 Judging by the logs, you should check if all imports that you use are properly installed in the init.ipynb file. Also note that it is a good practice when installing libriaries in the init.ipynb to specify the versions.

 @vyacheslav_b I also encountered this situation. Can you give more specific instructions on how the precheck file works? Thank you
